Having a TColorGridSeries, changing the LegendEvery property ends giving Access Violations and the application ends being unusable.

The exact you have to set on the LegendEvery property depends on the chart height.
Using the default chart height (250) it crashes when you set LegendEvery to 4.

  Chart1.View3D:=false;
  with Chart1.AddSeries(TColorGridSeries) as TColorGridSeries do
  begin
    FillSampleValues;
    UsePalette:=true;
    UseColorRange:=false;
    LegendEvery:=4; //Crashes for the default chart Height 250
  end;
