Description h.hasenack 2015-12-18 05:10:59 EST 
wrong legend item is highlighted when hoovering the mouse over a series

reproduce:
- Create a chart with 3 barseries, add random data
- close editor, check higlighting for the 3 series: all OK
- now de-activate the 1st series from within the editor
- Move mouse over the chart. Voila, the highlighter does not take into account the disabled series and huighlights series 3 when hoovering over series 2. But bars are highlighted correctly.

Adding a screenshot is a bit hard since it wond incorporate the mouse cursor.

Quite a chance I will provide a patch as well since I want it fixed today.

I have been trying to debug and fix this, but it appears to be quite hard. Maybe later. I Hope Steema will provide an "easy fix" soon.

Fixed. There was a missing check of series Visible, at Chart.pas:

   function NotLegendVisible(UpTo:Integer):Integer;
   var t : Integer;
   begin
     result:=0;

     for t:=0 to UpTo do
         if (not Series[t].Visible) or (not Series[t].Legend.Visible) then
            Inc(result);
   end;
