When you hover your cursor over a visualization, Grafana can display tooltips that contain more information about a data point, like the exact time of a result. You can customize tooltips to control how many series they include and the order of those values. You can also copy the content from tooltips to use elsewhere. Learn more about configuring tooltips in [Tooltip options](#tooltip-options).
## Supported visualizations
You can configure tooltips for the following visualizations:
Some visualizations, for example [candlestick](ref:candlestick) and [flame graph](ref:flame-graph), have tooltips, but they aren't configurable. These visualizations don't have a **Tooltip** section in the panel editor pane. [Geomaps](ref:geomaps) provide you the option to have tooltips triggered upon click or hover under the **Map controls** options in the panel editor pane.
Choose how tooltips behave with the following options:
- **Single** - The tooltip only the single series that you're hovering over in the visualization.
- **All** - The tooltip shows all series in the visualization. Grafana highlights the series that you are hovering over in bold in the series list in the tooltip.
- **Hidden** - Tooltips aren't displayed when you interact with the visualization.
When you set the **Tooltip mode** to **All**, the **Values sort order** option is displayed. This option controls the order in which values are listed in a tooltip. Choose from the following:
- **None** - Grafana automatically sorts the values displayed in a tooltip.
- **Ascending** - Values in the tooltip are listed from smallest to largest.
- **Descending** - Values in the tooltip are listed from largest to smallest.
When you set the **Tooltip mode** to **All**, the **Hide zeros** option is displayed. This option controls whether or not series with `0` values are shown in the list in the tooltip.
For the heatmap visualization only, when you set the **Tooltip mode** to **Single**, the **Show histogram (Y axis)** option is displayed. This option controls whether or not the tooltip includes a histogram representing the y-axis.
### Show color scale
For the heatmap visualization only, when you set the **Tooltip mode** to **Single**, the **Show color scale** option is displayed. This option controls whether or not the tooltip includes the color scale that's also represented in the legend. When the color scale is included in the tooltip, it shows the hovered value on the scale:
