Clipping problem with 3D surface

[PvdE]

When I set the minimum value for the bottom axis to a higher value, the left wall does not clip the chart.

To demonstrate, my form contains a commander bar and a chart edior. After the chart is shown, change the view such that you see the left wall clearly and press the button on the form to change the minimum value. When I use OpenGL, the problem is very visible.

Code: Select all

procedure TForm1.FormShow(Sender: TObject);
var
   mySeries: TSurfaceSeries;
begin
mySeries := TSurfaceSeries.Create(Chart1);
mySeries.FillSampleValues(50);
Chart1.AddSeries(mySeries);
Chart1.Legend.Visible := false;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
Chart1.BottomAxis.AutomaticMinimum := false;
Chart1.BottomAxis.Minimum := 10;
end;

Hi Paul,

I've been able to reproduce it using latest TeeChart Pro v7 VCL version (v7.04). However it only happens when using OpenGL. I've added this issue to our defect list to be fixed for future releases.

Narcis,

In the non- GL version, rotate the graph around (play with the view) and
I think you will see that the surface goes too 'high' (too deep from a 3D
point of view). It does not go through the wall as it does in the GL version.

Hi Paul,

Which TeeChart version are you using? I'm not able to reproduce that with our latest sources. The series seem to behave correctly when the bottom axis range changes. Could you please post some screenshots showing that error? You can post your files at [url]news://www.steema.net/steema.public.attachments[/url] newsgroup.
