Description kevin.persons 2022-04-20 12:50:40 EDT

The TCustomChartLegend.Clicked function does not consider whether the legend is visible when calculating its return value. As a result, when TCustomChart.MouseMove calls Legend.Clicked to determine a legend item hover status, the subsequent events that should be called by CheckMouseSeries do not fire in the case where the invisible legend occupies the same screen area as the hovered chart series. The fix I've applied to my copy of the source is to change the following line in TCustomChartLegend.Clicked from:
   if PointInRect(GetLegendBounds,P) then  
to:
   if Visible and PointInRect(GetLegendBounds,P) then
That seems to work for me, but maybe there are side effects that I haven't considered. Thanks.

Thank you very much, this is now fixed according to your "if Visible..." solution.
That check was missing.

Don't think it comes with any undesired side effect.
