Different gradient colors for different slices

[Tom]

Hi,

Is it possible to have a different gradient color for different slices?
For example: a pie chart with 3 slices:
slice 1: 30% red gradient,
slice 2: 50% green gradient,
slice 3: 20% orange gradient

also, is this possible with donuts?

another solution might be to have a third dimension for each slice.

Hi Tom,

I'm afraid that it wouldn't be easy to define custom gradients for each slice. But it would be easy if you could start with a shared color, white for example:

Code: Select all

uses Series, TeCanvas;

var pie1: TPieSeries;

procedure TForm1.FormCreate(Sender: TObject);
begin
  pie1 := TPieSeries.Create(nil);
  Chart1.AddSeries(pie1);

  pie1.Add(30,'',clRed);
  pie1.Add(50,'',clGreen);
  pie1.Add(20,'',RGB(255,128,64));

  pie1.Gradient.Visible := true;
  pie1.Gradient.StartColor := clWhite;
  pie1.Gradient.Balance := 100;
  pie1.Gradient.Direction := gdFromBottomLeft;
end;
