Description yeray alonso 2014-04-30 06:15:59 EDT 
Lots of changes were made in the Legend drawing between v2013.09 and v2014.10.
These changes make the example at "All features\Welcome\Miscellaneous\Legend\Multiple Legends" in the features demo to draw a strange Legend Rectangle for the second legend. See the image the customer attached in the forums.

I've seen this is because the ShapeBounds needs to be recalculated after assigning a new Series to the legend.

This could be related to http://bugs.teechart.net/show_bug.cgi?id=755

Can be fixed making TCustomChartLegend.CalcRect public and calling it in the AfterDraw event in the demo, after assigning Series2 and before DrawLegend:

  if CheckBox1.Checked then
  With Chart1.Legend do
  begin
    Top:=125;
    Series:=Series2;
    CalcRect;
    DrawLegend;
    CustomPosition:=False;
    Series:=Series1;
  end;
