Views and Charts
Overview
Apollo presents energy-market analysis through a collection of purpose-built Views. Each View is designed around a particular analytical question and determines which data, series, chart type, statistics, and viewer-specific controls are available.
The selected object in the Object Tree determines which Views are available. Selecting a different object can change the active View, replace the chart's series, update the legend, and change the units displayed on the axes. Switching Views can also replace the entire series set because each View reads and presents a different part of the scenario data.
Apollo's common chart engine is based on Highcharts. The natural chart type is normally determined by the active View and the available data. Chart Settings can provide a chart-type override for supported visual types, while certain viewers have their own specialized chart presentations such as boxplots, stacked areas, and Flow Duration Curves.
This page explains the common View and Chart system. For the detailed behavior of an individual View—including its series, statistics, data sources, limitations, and viewer-specific controls—refer to the corresponding Viewer Reference page.
Views
What Is a View?
A View is a named analytical presentation used by Apollo to answer a particular type of market or asset question.
For example:
- Net Load focuses on pool-level demand, VRE generation, residual load, and price.
- BidStack shows capacity distributed across bid-price tiers and can overlay generation.
- Fuel Summary shows generation by fuel type.
- Economics focuses on revenue, cost, profit, price, and generation.
- Storage shows charging, discharging, price, and storage level.
- Comparison lets you compare the behavior of the same object across scenarios.
- Flow Duration Curve shows the distribution of interconnector flow rather than a normal time series.
The View determines the analytical structure of the chart. It is therefore normal for the chart to look substantially different after changing Views.
Selecting a View
Available Views are presented in the Dashboard's View switcher / View tab bar above the chart area. The available list depends on the currently selected object and scenario.
When an object is selected, Apollo determines which Views are applicable to that object. A View that is not applicable may be unavailable or hidden rather than functioning as a valid analysis option.
The supplied source confirms that the View list varies by object type. For example, a Link can expose Link View and Flow Duration Curve View, while a Region can expose Fuel Summary and other region-oriented Views.
Selecting a View does not merely change the chart's appearance. It can load a different series set, change the Y-axis units, change statistics, and expose different toolbar controls.
Available Views
The Apollo reference set documents the following View types:
| View | What it is used for |
|---|---|
| Summary | Headline scenario and object information presented as tables rather than a chart. |
| Series Summary | Summary-oriented presentation for a series of results. The supplied source does not fully document its distinct interaction model. |
| Historical Database View | Inspection of historical database error records associated with the scenario. |
| Net Load View | Pool-level analysis of VRE generation, residual load, demand, generation, and price. |
| BidStack View | Site or Unit bid-price stack, generation, and related market information. |
| DGP View | Demand, generation, and price moving together over time. |
| Price, Generation + Demand View | Price, generation, and demand traces, including supported comparison behavior. |
| Fuel Summary | Generation split by fuel type for a Region. |
| Reserve Price View | Reserve-related price traces such as SMP, FRP, RUP, RDP, and DRP. |
| ProfilesView | Demand, generation, or price profiles by day type across a 24-hour day. |
| Link View | Flow and price-difference analysis across an interconnector. |
| Storage View | Storage charging, discharging, price, demand, and energy level. |
| Economics View | Revenue, cost, profit, price, and generation analysis. |
| Contract Settlement View | Contract price and settlement information, including contracted quantity. |
| AggregateStack View | Portfolio load stacks with generation and price overlays. |
| Sub-Group Trace | Demand and generation traces for PortfolioSubGroup members. |
| Regional Trace View | Price, demand, or generation across regions. |
| Zonal Trace View | Price, demand, or generation across zones in zonal scenarios. |
| Flow Duration Curve View | Distribution of link-flow values over the simulation. |
| Comparison View | Comparison of an object across multiple scenarios. |
Price Duration Curve View is inactive in the current source configuration and does not appear as an active viewer in the View switcher. The source specifically notes that its configuration is commented out. fileciteturn4file1L96-L110
Summary Is Different from Chart Views
Summary is not a normal chart viewer. It is a table-based viewer with no X axis, Y axis, chart type, chart series, zoom, tooltip, or chart export controls.
It has its own controls for:
- Price & Energy columns;
- Operation columns;
- Cost columns;
- object-type table visibility;
- All / None table controls;
- Site location filtering;
- Raw Data mode through the Create button.
These controls replace the normal chart-oriented toolbar behavior for Summary. fileciteturn4file6L456-L495
Historical Database View Is Also Table-Based
Historical Database View is also not a chart. It displays the contents of HistDBErr.csv, grouped by error type.
It provides error-type chips, All / None controls, summary counts, horizontal table scrolling, and table-level CSV export. Normal chart controls are hidden because there is no chart to configure. fileciteturn1file1L76-L129
Default View by Object Type
When you select an object in the Object Tree, Apollo can automatically open the View that best matches that object's data.
The documented default mappings include:
| Object type | Default View |
|---|---|
| Pool | Net Load View |
| Zone | Regional Trace View |
| Region | Fuel Summary |
| Site | BidStack View / Economics View — see note below |
| Unit | BidStack View |
| Portfolio | AggregateStack View |
| Storage | Storage View |
| Contract | Contract Settlement View |
| PortfolioSubGroup | Sub-Group Trace |
The source material contains a conflict for the Site default: the general Dashboard guide maps Site to BidStack View, while Viewer Reference B identifies Economics View as the default for Site objects. This should be verified against the running application before the Support Site presents one as definitive.
The other documented mappings are consistent across the supplied references. For example, Pool opens Net Load, Zone opens Regional Trace, Portfolio opens AggregateStack, Storage opens Storage, Contract opens Contract Settlement, and PortfolioSubGroup opens Sub-Group Trace. fileciteturn1file3L231-L248 fileciteturn3file0L23-L35 fileciteturn3file8L586-L604 fileciteturn3file7L510-L520
How the Chart Changes When You Work
A chart in Apollo is not a static object. Its series, axes, viewer, and statistics can change as you work.
Selecting a Different Object
When you select a different object in the Object Tree:
- The chart title changes to the selected object's name and type.
- The entire series set is replaced with data for the new object.
- The available Views may change.
- The legend is rebuilt for the new series set.
- The default View may change according to the new object's type.
This is why two objects can produce charts with completely different legends even when you have not manually changed the chart configuration.
Switching Views
When you switch Views:
- a different series set may be loaded;
- the Y-axis unit can change;
- the legend is rebuilt;
- statistics can change;
- viewer-specific controls can appear or disappear;
- the chart can change from a line to a stacked area, boxplot, Flow Duration Curve, or another supported representation.
For example, switching from a Demand/Generation/Price viewer to Fuel Summary replaces the demand and price lines with fuel-generation series. fileciteturn2file1L153-L159
Changing the Time Period
The ChartToolbar provides four standard time periods:
| Selector | Typical meaning |
|---|---|
| D | Daily |
| W | Weekly |
| M | Monthly |
| A | All / full scenario range |
Changing the period changes the visible time window and can change the data granularity.
| Period | Typical X-axis granularity |
|---|---|
| D | Trading intervals, typically 30-minute or hourly |
| W | Typically daily or interval data, depending on the View |
| M | Daily aggregates |
| A | Monthly or longer aggregates |
As granularity changes, a viewer may aggregate values or omit series that are meaningful only at a finer resolution. fileciteturn2file1L164-L175
Moving Through Time
Use the Previous, Next, or Date Picker controls to move the chart window through the simulation.
When you move to another period:
- the same series set is normally retained;
- values update to the new time window;
- an automatically scaled Y axis can change its range to fit the new data.
This automatic resizing is one of the main reasons Apollo provides Freeze Y Axes. fileciteturn2file1L177-L183
Comparison
When comparison is supported, Apollo can overlay scenario data for the same object.
The common object-comparison feature is available in:
- DGP View;
- ProfilesView;
- Reserve Price View;
- Economics View;
- Price, Generation + Demand View.
The Compare button is shown only when an object is selected and the active View supports comparison. fileciteturn2file3L261-L273
The separate Comparison View is a different feature. It compares the same object across scenarios and supports up to five additional comparison scenarios. It is manually selected and is not a default View. fileciteturn3file5L358-L373
Charts
Chart Types
Apollo's confirmed natural chart types include:
| Chart type | Typical Views |
|---|---|
| Line | Most time-series Views such as Demand, Generation, and Price traces |
| Stacked Area | Fuel Summary, AggregateStack, and other stacked generation views |
| Boxplot | ProfilesView |
| Flow Duration Curve | Flow Duration Curve View |
| Column / Stacked Column | BidStack View in supported configurations |
The current chart engine uses Highcharts. fileciteturn4file1L94-L110
Chart Type Override
Chart Settings provides a Type selector that can override the natural chart presentation.
The confirmed options are:
- Line
- Area
- Column
- Spline
Scatter, Step, and Horizontal Bar are not user-selectable chart-type options in the current source. fileciteturn4file1L96-L110
This override should not be confused with the specialized chart types used by viewers such as ProfilesView and Flow Duration Curve View.
ChartToolbar
The ChartToolbar is the control strip directly below the top bar and above the main chart area. It contains general chart controls plus controls that change depending on the active View.
The toolbar normally contains the selected object label, viewer-specific controls, Compare where supported, Summary's Create control where applicable, time navigation, chart actions, and the right-panel dock control. fileciteturn1file7L527-L540
Toolbar Control Reference
| Control | What it does |
|---|---|
| Object label | Shows the selected object's name and type. |
| Viewer-specific control | Changes depending on the active View. |
| Compare | Starts or exits supported object-comparison mode. |
| Create | Summary-only switch to Raw Data mode. |
| Date Picker | Selects the date/time window. |
| Previous / Next | Moves backward or forward by one period. |
| D / W / M / A | Selects Daily, Weekly, Monthly, or All. |
| Reset Zoom | Restores the full X and Y chart range. |
| Start at Zero | Forces the primary Y axis to start at zero. |
| Freeze Y Axes | Locks the current Y-axis range. |
| Axis Labels | Shows or hides axis label text. |
| Tooltip Location | Selects Right Panel, Follow Cursor, or Floating tooltip presentation. |
| Fullscreen | Expands the chart to browser fullscreen. |
| Reset Series Visibility | Restores all hidden legend series. |
| Export | Opens chart and data export options. |
| Chart Settings | Opens detailed chart customization. |
| Dock | Opens or closes the right panel when the active layout provides one. |
Viewer-Specific Toolbar Controls
The toolbar is deliberately adaptive. Some Views add controls that are meaningful only for that View.
Examples include:
| View | Viewer-specific control |
|---|---|
| BidStack View | Graph / Bid Table segmented control for supported Site, Unit, and Region contexts. |
| Comparison View | Chart / Summary switch; profile comparison can expose Day Type selection. |
| ProfilesView | Profile Type, Day Type, and Price-related options through its compact controls. |
| AggregateStack View | Mirror / Overlay mode. |
The Profiles controls are grouped into a compact dropdown so they do not overwhelm the toolbar at normal widths. fileciteturn2file3L245-L257
When Toolbar Controls Are Hidden
The toolbar does not show every control in every state.
The time-navigation group is hidden when:
- no object is selected;
- Summary is active;
- Historical Database View is active.
The action-button group is also hidden when there is no active chart viewer or when Summary / Historical Database View is active. The Date Picker is disabled in A / All because there is no narrower period to select. fileciteturn2file3L297-L313
This is expected behavior rather than a software error.
Using the Chart
Zoom In
To zoom into a time range:
- Move the cursor into the chart.
- Click and drag horizontally across the area of interest.
- Release the mouse button.
- Apollo zooms to the selected range.
A selection rectangle appears while dragging.
Reset Zoom
Click Reset Zoom to return the chart to its complete X and Y data range.
Reset Zoom affects the current chart zoom only. It does not reset chart settings such as colours or series styles. fileciteturn3file1L87-L95
Panning
Pan is not implemented as a separate first-class chart gesture. To move back out of a focused view, use Reset Zoom and then select another range. fileciteturn3file1L87-L91
Legend and Series
Showing and Hiding Series
When a chart has a legend, clicking a legend item toggles the corresponding series between visible and hidden.
Hidden series are tracked by chart type and remembered for the current session. fileciteturn3file1L97-L103
Reset Series Visibility
The Reset Series Visibility toolbar button restores all hidden series.
Its state indicates whether the chart currently contains hidden series:
| State | Meaning |
|---|---|
| Amber / active | At least one series is hidden |
| Dimmed | All available series are already visible |
This control affects visibility, not the underlying data.
Why Series Can Change
The series displayed by a View are determined by the selected object, active View, scenario contents, and sometimes the selected period or View-specific option.
For example:
- Net Load can hide the Price series and consequently remove the secondary price axis.
- Fuel Summary can contain one series for each available fuel type.
- AggregateStack creates demand series based on Portfolio membership and can omit generating sites with all-zero generation.
- Flow Duration Curve data comes from a pre-computed FDC file rather than live time aggregation.
These are View-specific behaviors, not anomalies in the chart engine. fileciteturn4file9L631-L681 fileciteturn3file8L607-L626 fileciteturn3file6L443-L480
Tooltip
Move the cursor over a chart to inspect the values of the visible series at that X-axis position.
A tooltip can show:
- the X-axis label or timestamp;
- series colour;
- series name;
- formatted series value.
The Tooltip Location control provides three modes:
| Location | Behavior |
|---|---|
| Right Panel | Values appear in the right-side contextual panel. This is the default. |
| Follow Cursor | A traditional tooltip follows the cursor over the chart. |
| Floating | A draggable tooltip stays inside the chart. Its position is remembered between sessions. |
The Floating tooltip can be reset to the top-right position by double-clicking its drag handle. fileciteturn3file1L105-L122
When Right Panel mode is active, the data card can display up to 20 visible series. If more series are available, Apollo shows a "+N more" indicator. fileciteturn1file7L554-L562
Axis Controls
Start at Zero
Start at Zero changes the Y-axis minimum to zero instead of the automatically fitted minimum.
This is useful when comparing absolute magnitudes rather than only the relative movement of a series.
The setting is stored separately by viewer. BidStack and Fuel Summary default to Start at Zero on, while Link View defaults to off because link flows can be bidirectional and may include negative values. fileciteturn2file1L97-L110
Freeze Y Axes
Freeze Y Axes captures the current Y-axis range and keeps that range while you navigate through periods or scenarios.
Recommended workflow:
- Navigate to a representative period.
- Adjust the visible chart until the desired Y range is shown.
- Activate Freeze Y Axes.
- Navigate through other periods.
- Compare the chart using the same visual scale.
- Disable Freeze Y Axes when automatic scaling is wanted again.
The freeze state is tracked separately for standard viewers, Comparison View, and ProfilesView. fileciteturn2file1L110-L122
Axis Labels
Axis Labels toggles the axis-label text, including axis names and units. It does not remove the numerical scale values or grid lines. fileciteturn3file1L120-L122
Chart Settings
The Chart Settings panel contains configuration that is more detailed than the quick toolbar controls.
Primary Axis
The Primary Axis section provides:
| Setting | Meaning |
|---|---|
| Auto Scale | Automatically fits the primary Y axis to the visible data. |
| Min | Manual minimum when Auto Scale and Freeze are not active. |
| Max | Manual maximum when Auto Scale and Freeze are not active. |
Secondary Axis
The Secondary Axis section appears only when the chart has a dual Y axis.
It provides:
- Lock to Primary;
- Auto Scale;
- Min;
- Max.
Auto Scale is disabled when Lock to Primary or Freeze is active. fileciteturn2file0L11-L32
Level Axis
Storage View has a separate Level Axis because storage level is measured differently from the MW traces.
The Level Axis provides its own Auto Scale and Min / Max controls. fileciteturn2file0L27-L32
Grid Lines
Apollo provides four independent grid-line controls:
| Setting | Default |
|---|---|
| Y Major | On |
| Y Minor | Off |
| X Major | Off |
| X Minor | Off |
Major lines correspond to labelled tick positions; minor lines provide smaller subdivisions. fileciteturn2file0L36-L47
Visual Settings
The Visual section provides:
- Axis Labels — On by default.
- Animations — On by default. Turning them off can improve performance on large datasets.
- Type — chart-type override with Line, Area, Column, and Spline. fileciteturn2file0L51-L57
Series Settings
The Series section appears when at least one chart series is loaded.
Each series is shown with:
- a visibility checkbox;
- a colour swatch.
A Show All button appears when a series is hidden.
This is equivalent to controlling visibility through the chart legend. fileciteturn2file0L61-L65
Legacy Statistics Display
Chart Settings can expose a compact read-only Statistics section containing Min, Max, and Average for Price, Demand, and Generation when those values are available.
This is secondary to the main statistics bar below the chart. fileciteturn2file0L69-L71
Chart Layout
Apollo supports two chart-area layouts.
Layout 1 — Chart + Stats + Right Panel
- Main chart in the centre.
- Statistics bar below the chart.
- Right panel for tooltip data, statistics detail, fuel mix, and other contextual information.
Layout 2 — Chart + Two Lower Panels
- Right panel is removed.
- Dock button is hidden.
- Lower area is divided into two panels.
- Provides additional horizontal space for chart/detail presentation.
The layout is stored per viewer and persists between application restarts. fileciteturn4file4L276-L335
Overlay Opacity
Overlay Opacity controls the background opacity of in-chart overlays such as:
- chart title overlays;
- floating tooltip boxes.
Separate controls are provided for Light and Dark themes, with values from 0 (transparent) to 1 (fully opaque). fileciteturn2file0L88-L94
Reset All Settings
Use Reset All Settings when you want to restore Chart Settings to their factory defaults and clear saved axis state.
This is different from Reset Zoom, which only restores the chart's zoom range.
Statistics
Statistics are calculated by the active View from the chart data currently loaded. They update when the selected object, period, or scenario data changes. fileciteturn4file7L528-L549
Statistics Bar
In Layout 1, stat cards appear below the chart. In Layout 2, they appear in the lower panel.
A stat card can contain:
- a label;
- a primary value;
- optional supporting information such as sample counts or percentages.
Clicking a stat card opens a Stat Detail card in the right panel when the active View supports it.
The detail card can contain values such as Min, Max, Count, Sum, and Standard Deviation, depending on the View and statistic type. fileciteturn4file7L540-L566
Viewer-Specific Statistics
Statistics are not identical across Views.
For example:
- Net Load provides Average Price, Total VRE Generation, and Total Net Load.
- ProfilesView provides 24 hourly statistic cards based on median profile values and sample counts.
- Flow Duration Curve provides Peak Flow, Median Flow, Capacity Use, and Flow Range.
- Economics provides Generation, Avg Price, Revenue, Cost, Profit, Margin, fuel-type statistics, and station breakdown information.
Refer to each Viewer Reference for the exact statistics available in that View. fileciteturn4file9L642-L653 fileciteturn1file8L589-L625 fileciteturn4file2L38-L57 fileciteturn1file4L291-L328
View-Specific Chart Behavior
Although all chart Views share the common ChartToolbar, each View can impose its own rules.
BidStack View
BidStack is a stacked representation of bid-price buckets. It can include a Generation line and, for Site data with DGP overlays, Demand and Price lines.
The toolbar can switch between Graph and Bid Table for supported objects. The Bid Table shows the underlying bid rows for the current period, with columns derived from the scenario's bid CSV. fileciteturn1file5L400-L428
Net Load View
Net Load uses stacked VRE Generation and Residual Load areas with Demand, Generation, and Price overlays.
Hiding Price removes the secondary Price axis. Hiding VRE Generation or Residual Load changes the visible stacked total. fileciteturn4file9L631-L681
Fuel Summary
Fuel Summary uses a stacked area chart with one series for each fuel type present in the selected Region.
Fuel colours are viewer-specific and are not necessarily interchangeable with general series-colour customization. Refer to the Fuel Summary guide for its fixed fuel palette and rules.
AggregateStack
AggregateStack creates its series from Portfolio membership. Each Load member can contribute a demand area, while generating Site members with non-zero generation can contribute generation lines. There is no user-facing series filter within this View; navigate to the member object itself when you need a dedicated member-level analysis. fileciteturn3file8L586-L644
ProfilesView
ProfilesView is not a normal time-series chart.
Its X axis is always the 24 hours of the day, and its primary representation is a boxplot showing the distribution of values for each hour.
Its toolbar therefore uses Profile Type and Day Type controls instead of the normal D/W/M/A time navigation. It still supports Reset Zoom, Start at Zero, Freeze Y, Axis Labels, Tooltip, Export, Chart Settings, Reset Series Visibility, and comparison. fileciteturn1file8L589-L631
Flow Duration Curve View
Flow Duration Curve View is also different from ordinary time-series Views.
It plots sorted flow values against percentage of time exceeded. Its source is a pre-computed FDC_<ID>.csv, so D/W/M/A does not behave like normal time-series navigation and may not change the displayed data. fileciteturn3file6L443-L480
Regional and Zonal Trace Views
Regional Trace and Zonal Trace use line charts with one series per region or zone and allow a trace-type selector for Price, Demand, or Generation.
Zonal Trace is only visible in zonal scenarios and is not the default View for any node type. fileciteturn3file7L510-L557
Series Customization
Legend Interaction
Left-clicking a legend item controls visibility.
- Click once to hide the series.
- Click again to show it.
- Use Reset Series Visibility to restore every hidden series.
The common chart reference confirms this as standard legend behavior across chart Views. fileciteturn4file1L122-L128
Context Menu Customization
The supplied source set identifies series styling as part of Apollo's chart-customization system, but the common Charts and Toolbars reference does not provide a fully verified control-by-control specification for the right-click context menu.
Therefore, the following details from the draft page should be treated as pending running-application verification before becoming permanent Support Site claims:
- Right-clicking a legend item to open the context menu;
- Isolate Series / Restore All Series;
- Series Type options specifically containing Area Spline;
- exact Line Width values;
- exact Dash Style menu entries;
- Markers toggle;
- 20-colour palette;
- Reset to Original;
- Reset All Series;
- disabling Series Type specifically for stacked charts;
- localStorage persistence keyed by chart view and series name;
- sessionStorage persistence for isolation state.
The common reference does confirm that Chart Settings has series visibility controls, but the exact right-click implementation and persistence model for individual series styling were not established in the supplied source material. Do not publish those details as verified behavior until they are confirmed against the running Apollo application.
Exporting Charts and Data
The Export button provides both visual chart exports and underlying data exports.
| Option | Result |
|---|---|
| Print chart | Opens the browser print dialog. |
| Download PNG | Visual chart image with transparent background. |
| Download JPEG | Visual chart image at a fixed 16:9 resolution of approximately 1920 × 1080. |
| Download PDF | Visual chart in A4 dimensions. |
| Download SVG | Vector chart export. |
| Download CSV | Underlying chart data. |
| Download XLSX | Underlying chart data in Excel format. |
| Toggle fullscreen | Enters or exits fullscreen mode. |
PNG, JPEG, PDF, and SVG represent the chart as rendered, including visible series, legends, and axis labels. CSV and XLSX contain the underlying numeric data for the series currently on the chart. fileciteturn4file1L124-L128
Fullscreen
Click the Fullscreen control to make the chart fill the browser window.
To exit fullscreen:
- click the Fullscreen control again;
- press Escape;
- or use the fullscreen option in the Export menu.
Fullscreen is useful when reviewing dense charts, inspecting data points, or preparing a chart for presentation. fileciteturn4file1L118-L120
Understanding Why a Control Is Missing or Disabled
A missing or dimmed control is often intentional.
Check the following before treating it as a problem:
- Is the correct object selected? Some Views are only available for particular object types.
- Does the selected scenario support that View? Zonal Trace, for example, is only available in zonal scenarios.
- Does the View support the feature? Net Load does not support comparison mode, while DGP and certain other Views do.
- Is there an active chart? Some controls are unavailable while a viewer is loading.
- Is the current layout Layout 2? The right-panel Dock button is hidden because Layout 2 has no right panel.
- Is the selected View table-based? Summary and Historical Database hide the normal chart controls.
- Does the chart actually contain the feature? Secondary-axis and Level-axis settings only appear where the relevant axes exist.
This adaptive behavior is part of Apollo's interface design. fileciteturn2file0L19-L32 fileciteturn2file3L297-L313
Practical Workflows
Quickly Inspect One Metric
- Select the required object.
- Select the View that contains the desired metric.
- Hide unnecessary legend series.
- Use the Tooltip Location control to choose Right Panel, Follow Cursor, or Floating.
- Zoom into the period you want to inspect.
- Click Reset Zoom when finished.
Compare Different Time Periods
- Choose the appropriate D/W/M/A period.
- Navigate to a representative period.
- Adjust the chart scale as needed.
- Activate Freeze Y Axes.
- Move through other periods with Previous / Next.
- Compare the charts using the same Y-axis scale.
Prepare a Chart for Presentation
- Select the relevant View and object.
- Hide unnecessary series.
- Adjust Axis Labels and grid lines to reduce clutter.
- Choose the most useful chart layout.
- Configure the tooltip or close the right panel if it is not needed.
- Enter Fullscreen.
- Export to PNG, JPEG, PDF, or SVG.
Compare Scenarios
- Select the object to be compared.
- Activate a View that supports comparison or switch to Comparison View.
- Add the required comparison scenario(s).
- Select the comparison metric.
- Use the chart and statistics to examine differences.
- Remove comparison scenarios when finished or switch back to the normal View.
Comparison View allows up to five additional scenarios and uses the first scenario as the primary baseline. fileciteturn3file5L364-L373
Common Questions
Why did my chart change completely after selecting another object?
Selecting an object rebuilds the series set and can also change the default View. The new chart is based on that object's available data.
Why did the Y axis change when I clicked Next?
The chart normally uses automatic Y-axis scaling. A new period can contain a different data range, so Apollo rescales the axis to fit that period. Use Freeze Y Axes when you need a consistent scale across periods.
Why did the Price axis disappear?
In Views with an optional Price series, hiding or losing the Price series can also remove its secondary Y axis. Net Load is a documented example. fileciteturn4file9L631-L681
Why is D/W/M/A not available?
Summary and Historical Database View have no time-series chart, so those controls are hidden. ProfilesView uses a fixed 24-hour X axis and therefore does not use D/W/M/A. Flow Duration Curve uses a pre-computed duration file and does not respond to D/W/M/A like a normal time-series chart. fileciteturn1file0L390-L395 fileciteturn1file8L601-L618 fileciteturn3file6L475-L480
Why can't I compare this View?
Not all Views support object comparison. The common comparison button is only exposed for DGP, Profiles, Reserve Price, Economics, and Price, Generation + Demand. fileciteturn2file3L261-L273
Why can't I find Price Duration Curve?
The current source identifies Price Duration Curve View as inactive and commented out in the current configuration. It therefore should not be presented as an active selectable View. fileciteturn4file1L96-L110
Why does a View have different series in a different scenario?
The series available to a View depend on the data actually produced by the scenario. A scenario can have different fuels, objects, outputs, or columns than another scenario, which can change the series available for display.
