One More FMX vs VCL Chart Help

Hi,

I am stuck on the labels with the pie and also on the legend. Below are two screen grabs - one from the VCL version which shows it as I need to show it. The other is from the FMX version that is incorrect. I can't see any difference in the properties between the two versions. FMX just does things differently and I am not able to figure this out.

In the VCL version, you'll note that the legend shows a range of dollars donated, which is correct. It also shows another number in the legend, which represents the total dollars given from that range.

In the FMX version, I cannot seem to find how to get the pie chart's labels to show as $ (dollars), and the amounts on the legend also don't show as dollars. I've searched the help files but don't see how to set the marks for currency. Any help appreciated.

John

Oops - sorry, I uploaded the wrong file. Here's the correct FMX file that shows the labels without the dollar signs that I referenced above.

Hello,

TeeChart converts the values to strings using the series ValueFormat, which is by default '#,##0.###'. You can add the '$' before it and it will do what you want. Ie:

Code: Select all

procedure TForm1.FormCreate(Sender: TObject);
begin
  Series1.AddPie(561, '$1.00 to $25.00');
  Series1.AddPie(909.5, '$26.00 to $50.00');
  Series1.AddPie(365, '$51.00 to $100.00');
  Series1.AddPie(3545, '$101.00 to $1,000.00');
  Series1.AddPie(2500, '$1,001.00 to $10,000.00');

  Series1.Marks.Style:=smsValue;
  Series1.ValueFormat:='$'+Series1.ValueFormat;
end;
