Description Lee M 2015-03-13 11:09:27 EDT 
Using Delphi XE7 using build January 23, 2015.

I have unit that I have been using for many years. With this latest build, it raises an exception.

On the form I have a TChart and the following series:
    PieSeries1: TPieSeries;
    Series1: TPointSeries;
    Series2: TLineSeries;
    Series3: TBarSeries;
    Series4: TBarSeries;
    Series5: TBarSeries;
    Series6: TBarSeries;
    Series7: TBarSeries;

I have a routine that displays what series I want displayed by setting the visible property:

procedure TfmGraphs.SetupSeries(Const idx : integer);
begin
  Case idx of
    0  : begin//Displays Pie Graph
           Series1.Visible := false;
           Series2.Visible := false;
           Series3.Visible := false;
           Series4.Visible := false;
           Series5.Visible := false;
           Series6.Visible := false;
           Series7.Visible := false;
         end;
    1  : begin//Displays Series Graph
           Series1.Visible    := true;
           Series2.Visible    := true;
           PieSeries1.Visible := false;
           Series3.Visible := false;
           Series4.Visible := false;
           Series5.Visible := false;
           Series6.Visible := false;
           Series7.Visible := false;
         end;
    2  : begin//Displays 1 Bar Graph
           PieSeries1.Visible := false;
           Series1.Visible := false;
           Series2.Visible := false;
           Series4.Visible := false;
           Series5.Visible := false;
           Series6.Visible := false;
           Series7.Visible := false;
         end;
    3  : begin//Displays 5 series of bar graphs
           PieSeries1.Visible := false;
           Series1.Visible := false;
           Series2.Visible := false;
         end;  
  end;
end;

When I call SetupSeries(1) and then fmGraphs.ShowModal it raises an exception.

Thank you,
Lee

Click the button on the main form and trace the code

There is too a bug.
 
When I run this test project using TeeChart 2014 for Delphi XE7 it runs fine.
 
When I run it using using TeeChart 2015 for Delphi XE7 there is an exception raise.
 
Simply click the button on the main form and trace the code.
 
You will need to change the path where the files are stored in the Project.

Hello Lee, 

Thanks for the project. The problem only occurs if you add the Series in designtime, if you add the Series by code the exception disappears. 

Thanks in advance,
regards.

Cannot reproduce the problem with latest TeeChart version.
