Tooltips appear when a user hovers over a data point in a chart. By default, Cube automatically populates the tooltip with all fields mapped to chart channels. You can customize which fields are shown and in what order.
When a chart is first created, all fields assigned to the chart (X, Y, color, size) are included in the tooltip automatically. The tooltip is enabled by default on all Vega-based chart types (bar, line, area, scatter, heatmap, boxplot) and on map charts.
Open the Fields tab of the chart configuration panel. The Tooltip section shows the list of fields currently included in the tooltip.
| Action | How |
|---|---|
| Add a field | Drag a field from Available fields into the Tooltip slot |
| Remove a field | Click the × on a field token in the Tooltip list |
| Reorder fields | Drag field tokens within the Tooltip list |
To turn off tooltips entirely, remove all fields from the Tooltip slot. When the Tooltip slot is empty, no tooltip is shown on hover.
On stacked bar charts, the tooltip is scoped to the individual stack segment under the cursor — it shows the value for that specific series at that X position, not the total stack value. To display the stack total, use data labels with the Simple totals option.
