Tooltips appear when a user hovers over a data point in a chart. By default, Cube populates the tooltip with the fields the chart draws. You can pick which of the query’s columns are shown.

​
Default behavior

When a chart is first created, the fields it draws are included in the tooltip automatically. Tooltips are enabled by default on bar, line, area, scatter, heatmap, and boxplot charts, on map charts, and on sankey charts. Sankey is the exception to the first rule: it seeds the tooltip with every column except the source, target and value it already draws.

​
Configuring tooltip fields

Open the Fields tab. The Tooltips row summarizes the current selection — All fields, N fields, or None. Open it for a checkable list of the query’s columns, dimensions first, and check or uncheck the ones you want. On a bar, line, area, or scatter chart the selection applies to the whole chart, not to one measure.

​
Disabling tooltips

Uncheck every field to turn tooltips off. No tooltip is shown on hover while the list is empty.

​
Tooltip behavior on stacked charts

On stacked bars, the tooltip is scoped to the individual stack segment under the cursor — it shows the value for that series at that position, not the total. To show the total, turn on data labels, which label a bar with its total at the end of the bar.
