The slices of the pie chart do not update in D2007 TC7.11 PRO. The AddPie function works to initially add slices to the chart, but then updates to the values are not reflected except by the chart labels and legend.

This occurs in code and through the chart editor in both run and design times, and on several computers.

Plugging in a bar chart into the same form/code (changing the addpie call to addbar) works fine.

The code was recently migrated from Delphi 7 (TC 7.04 PRO) where it was working and stable for a number of years.

Delphi version - 11.0.2709.7128
Platform - XP SP2

I've tried quite a few tacts to try and work this one out so any help/advice would be greatly appreciated.

Hi Daniel,

I could reproduce the issue here using v7.12 and this code:
I've also checked that this code works fine with TeeChart Pro v8 VCL.

Thanks for the prompt reply.

Will there be a patch for version 7.12?

Hi Dan,

I think it's most unlikely that a new TeeChart v7 release will be published.

procedure TForm1.Button1Click(Sender: TObject);
begin
  Series1.AddPie(random*10);
end;

The code works in Delphi 2006, but this did not work:

procedure TForm1.FormCreate(Sender: TObject);
var i: Integer;
begin
for i:=1 to 5 do
begin
Series1.AddPie(i);
update;
end;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
Series1.AddPie(random*10);
end;

Could it be verified that this code works in v. 8?

Hi achristouio,

Yes, I've checked that this works fine using v8.

I would expect that an update or patch is released. Steema has released an update that has stopped the pie chart from working entirely. I'm not seeking new functionality (which might warrant an upgrade to the next major release). I'm just expecting that previously working v7 functionality be fixed so that it is working again.

Hello Daniel,

We have just posted an update build for Delphi 2007 fixing this issue at the client area.

Thanks Narcís,

It all works now - I'm grateful to you and the Steema team for fixing this issue,

Hi Daniel,

You're welcome. I'm glad to hear that.
