Chart Controls
Most Tunny Dashboard charts share one of two interaction systems: a 2D system for flat charts and a 3D system for charts with an arcball camera. The point, legend, and selection interactions on top of them are common too. This page documents all of them once; individual widget pages link here and describe only their own widget-specific controls (axis selectors, toggles, and what each tooltip shows).
2D charts
Applies to the flat charts — Pareto Scatter 2D, Optimization History, Convergence Indicators, Intermediate Values, Timeline, EDF, Rank Plot, Slice Chart, Observed Contour, MCDM Scatter Chart 2D, Cluster Scatter 2D, the statistics charts, and the surrogate fit/overlay plots.
| Action | How |
|---|---|
| Zoom | Scroll the mouse wheel to zoom centered on the cursor, or drag with the left button to box-zoom into the selected rectangle. |
| Pan | Drag with the right mouse button. |
| Reset view | Double-click with the left button to restore the default (auto-range) view. |
Points & legend
Charts that plot individual trials or several series add these on top of the 2D navigation:
| Action | How |
|---|---|
| Hover | Hover over a point, curve, or bar to see a tooltip. What the tooltip lists is chart-specific and is noted on each widget's page; on some charts the hovered series is highlighted and the others dimmed. |
| Trial detail | Left-click a point to open the trial detail modal for that trial (objective and parameter values, plus any attached artifacts). |
| Toggle series | Click a legend entry to show or hide that series. |
| Region select (brush) | On scatter charts that support it, hold Shift and drag with the left button to select a rectangular region and highlight the enclosed trials; click blank space to clear. This selection is shared across charts — the highlighted trials stay highlighted on the other widgets, and points outside it are dimmed rather than hidden. |
3D charts
Applies to the arcball-camera charts — Pareto Scatter 3D, Response Surface 3D, Cluster Scatter 3D, MCDM Scatter Chart 3D, and PDP Chart 2D.
| Action | How |
|---|---|
| Rotate | Right-click and drag (arcball rotation). |
| Pan | Middle-click drag, or Shift + right-click drag. |
| Zoom | Scroll the mouse wheel. |
| Hover | Hover over a point to show its tooltip. |
| Trial detail | Left-click a point to open its detail modal. |
Charts with their own controls
A few widgets do not use either system and document their controls on their own page:
- Parallel Coordinates uses per-axis brushing instead of pan/zoom.
- Grid and table widgets (Sensitivity Heatmap, Correlation Matrix, Comparison Table, Trial Table) are static — they have no navigation.
