Tooltips

Control which fields appear when a user hovers over a chart mark.

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.

Default behavior

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.

Configuring tooltip fields

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

Disabling tooltips

To turn off tooltips entirely, remove all fields from the Tooltip slot. When the Tooltip slot is empty, no tooltip is shown on hover.

Tooltip behavior on stacked charts

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.
