Display shared tooltip for all categories

Updated on Dec 19, 2025

Environment

Product Version	10.2.0
Product	Progress® KendoReact HeatMap

Description

I have a HeatMap with multiple categories, but the shared tooltip render only the hovered value category.

Solution

The behavior is expected and in order for the tooltip to display all category values, use custom rendering for the ChartTooltip and manually search for all values from the categories matching the x value of the hovered point.
