Lots and lots of bar colours

[Mortong]

Good afternnon

Thank y'a;; for your pervious help.

If I have say 150 bars then the colours seem to fizzle out after say 15, can I reuse the same sequence so it looks pretty as opposed to red,green, blue, cyan, orange,orange,orange,orange,orange....

Hi Morton,

I guess the only way to change this is to change source code and recompile TC packages (if you are source code customer). Or create your
custome array of colors.

Erm, like how please....

Hi Morton,

you can define your custom Array of colors and use it like in the following code :

Code: Select all

Const ColorP:Array[1..10] of TColor=
        ( clRed,
          clGreen,
          clYellow,
          clBlue,
          clWhite,
          clGray,
          clFuchsia,
          clTeal,
          clNavy,
          clMaroon
          );

procedure TForm1.FormCreate(Sender: TObject);
var i,c : integer;
begin
c:= 0;
for i := 0 to 19 do
begin
  if i mod 10= 0 then c:= 1
  else c:= c+1;
  Series1.AddXY(i,random(10),'',ColorP[c]);
end;
end;

Hi Josep,
Instead of using an array of colours, would it not be better to use the custom palette method? Could you please give an exmple using TChartSeries (Bar or something) with custom palette?

Regards john.

Hi john,

in TeeChart v6 and above the ColorPalette is declared as
var ColorPalette:Array of TColor;

so you can simply access/change color palette without need to recompile TeeChart sources.
