title: Tooltip following wrong RadzenAreaSeries
labels: ''
assignees: ''


Describe the bug
When having several RadzenAreaSeries in one RadzenChart, the tooltip does not show data for the AreaSeries currently being hovered over.

To Reproduce
Steps to reproduce the behavior:

  1. Create a RadzenChart
  2. Add at least two RadzenAreaSeries
  3. Hover with the mouse over the different AreaSeries

Expected behavior
See a Tooltip with data for the AreaSeries currently being hovered.

Screenshots
radzen

Image caption: While the mouse is hovering the yellow area, the tooltip follows the purple area.

Desktop (please complete the following information):

  • Browser [chrome]

Additional context
Seems to be the same problem with RadzenLineSeries when overlapping AreaSeries as well. Changing the RenderingOrder does not solve the problem. It might seem like the Tooltip is stuck with the wrong RenderingOrder, i.e. the Tooltip is not following the Series rendered at top.
