Crash when using Pie Chart

[JeffS]

Hi,

I am porting an application from Codegear 2007 to XE4. We have acquired the full version of Teechart.

But the use of TPieSeries in our dfm file, causes the crash of our application (though it was working fine when compiled with 2007 tools and librairies).


Here is the call stack:

:00536577 TfrmSelectGraphType::TfrmSelectGraphType(this=:03402250, rptWin=:04346230, dlgDefineGraph=:042F6F80)
...

and here is the extract of the faulty code in the dfm file:
object serPieGraph: TPieSeries
Marks.Arrow.Visible = True
Marks.Callout.Brush.Color = clBlack
Marks.Callout.Arrow.Visible = True
Marks.BackColor = clSilver
Marks.Color = clSilver
Marks.Style = smsXValue
Marks.Visible = True
Gradient.Direction = gdRadial
OtherSlice.Legend.Visible = False
OtherSlice.Text = 'Other'
PieValues.Name = 'Pie'
PieValues.Order = loNone
end


Do you have an idea of what happens ?

Hi,

What version where you using with RAD 2007?
Have you tried to remove line per line those you've posted to try to identify which one is causing the problem?
Does the error also appear if you create a new simple application with just a chart on the form? And adding a simple Pie?

Hi,


>> What version where you using with RAD 2007?
TeeChart 8.02 for Delphi 2007


>> Have you tried to remove line per line those you've posted to try to identify which one is causing the problem?
Yes. Even if I remove all the lines except the declaration of Pie, the crash happens.
In other words, the simple fact to mention TPieSeries in the dfm file
(for intance:
object serPieGraph: TPieSeries
end
)
causes the crash.

I am ashamed to say that I am not used to this kind of excercice. I am in charge of porting the application to the new version of the Embarcadero builder.
I never wrote an application using your library from scratch. But I can learn...

Hi Jeffs,

Hi,
TeeChart 8.02 for Delphi 2007

What about with latest v8 release or current v2013? Have you had the change to test them?

I am ashamed to say that I am not used to this kind of excercice. I am in charge of porting the application to the new version of the Embarcadero builder.

It's something very easy. Having a look at the tutorials included with the binary installers will help you getting started.

Thanks in advance.
