Data Wells
- Axis — Categorical field for bar grouping
- Values — One or more measures displayed as bars
- Legend — Grouping field to split bars into colored series
- Series Color — Hex color codes per series
- Logo — Base64 images per series
- Error Bar Upper/Lower — Measures for error bar bounds
Selection & Cross-Filtering
Clicking on bars cross-filters other visuals on the report page.
| Action | Behavior |
|---|---|
| Click a bar | Selects that single data point |
| Ctrl+Click (Cmd+Click on Mac) | Adds or removes individual bars from the selection |
| Alt+Click a bar | Selects all bars of the same series (Legend value) across every category |
| Click empty area | Clears the selection |
Alt+Click is only available when a Legend field is assigned. It is useful for cross-filtering an entire series at once rather than selecting bars one by one.
