Before:


Now:


Will the shadow be corrected in the official release version?

best regards.

Hello Marder,

I am using the Delphi XE2 prerelease of TreeChart Pro V2011 and just wanted to report that the shadow of a bar series is looking quite strange with this version.

You are right, it worked fine in v2011.03 but in v2011.04. I've added it to the defect list to be fixed asap (TV52015903).
PS: I assume you meant "pie series" where you said "bar series", according to the pictures.

Hello Yeray.

I assume you meant "pie series"

Yes, I meant "pie"

I've added it to the defect list to be fixed asap

Could you please send me a fixed prerelease version when you have fixed this issue?
This would be great!

Best regards.

I have logged your request in the issue description.

Hi.

I wonder if there might be a fix for this issue in the official release of the upcoming V2012.07?

Best regards.

Hi marder,

Build 2012.07.121105, the version we published yesterday, is the official 2012.07 release.

The bug hasn't been fixed yet but we found where the problem is. Since you are a source code customer you may want to try implementing TTeeCanvas3D.SmoothShadow at TeCanvas.pas like this:

Code: Select all

procedure TTeeCanvas3D.SmoothShadow(Shadow:TTeeShadow; const Rect:TRect;
                             Ellipse:Boolean; RoundSize:Integer;
                             const P:Array of TPoint;
                             DonutPercent:Integer=0;
                             const Z:Double=0);
begin
  if Shadow.Smooth and (not Metafiling) {$IFNDEF FMX}and Assigned(FBitmap){$ENDIF} then
     Shadow.InternalDrawSmooth(Self,
                               CalcRect3D(Rect,Round(Z)),
                               Ellipse,RoundSize,P,DonutPercent)
  else
     inherited;
end;

That's similar to how it was implemented before introducing the bug. Now we will investigate the reason for this change and try to find a permanent fix for the issue.

Hi Narcis.

I downloaded final version V2012.07.
After installation I run "TeeRecompile.exe" and get the following error:

===============================================
TeeChart Pro
Compilation started: 09.11.12 13:39:22

RAD XE2.Win32 v16 Architect (RAD XE v9 Architect)
EXCEPTION:
Text: unit TeeChart not found in TeeChart.pas
--------------------------------------------


How can I get it to run?

Best regards.

Hi Marder,

Please, remove the TeeChart.pas file and try it again.

Hi Yeray,

Thank you that worked.
The shadow is again drawn as expected.

Please let me know when there is a new maintenance release including this fix.
Until then I will use the customization.

Best regards.

Hi marder,

As an update, TV52015903 has been fixed for the next maintenance release. The fix is at the TPieSeries.DrawAllValues method, in Series.pas:

Code: Select all

  if FShadow.Visible then
     FShadow.DrawEllipse(ParentChart.Canvas,
                         ParentChart.Canvas.CalcRect3D(CircleRect,tmpShadowZ),
                         tmpShadowZ,DonutPercent);

You should remove the change I suggested in TeCanvas.pas and change FShadow.DrawEllipse call as shown above.

Dear Narcis.

Thank you!
I will give this a try soon.

Best regards

[marder]

Dear Narcis.

The new fix seems to work correctly.
Thanks for your help!

Best regards.

Dear Marder,
