Change Tooltip title in Power BI Native Gantt Chart Visual

Hi evek ,
In the native Power BI Gantt chart, the Resource title in the tooltip is fixed and cannot be renamed directly from the visual settings. However, you can completely bypass it using a custom tooltip report page.

Steps:

Create a new report page in Power BI Desktop.

In Page Information, turn Tooltip = On and set page size to Tooltip.

Design this page with the fields you want and your own titles.

Open your Gantt chart, then navigate to the Format pane, select Tooltip, and go to Options.

Change Type from Default to Report page.

Select your custom tooltip page from the dropdown.

Now, when you hover over the Gantt visual, only your designed tooltip will appear the default Resource label will no longer be shown.
