TeeChart 8.05: Fixed pixel interval between major ticks

[OCS]

Hello,

is it possible to have a fixed pixel interval (say 150px) between horizontal major ticks? If the user resizes the form (and the chart within), labels are rearranged and sometimes look odd.
My goal is to place a label at each major tick every 150 pixels, so resizing the chart does not make the labels jump.

Regards,
Guido

Hello Guido,

I have made a simple example for you using OnGetAxesLabels:

Code: Select all

var
  Form1: TForm1;
  AntValue:Integer;

implementation

{$R *.dfm}
uses Series;

procedure TForm1.FormCreate(Sender: TObject);
var Series1:TLineSeries;
    i:Integer;
begin
  AntValue:=0;
  Series1 := TLineSeries.Create(self);
  Chart1.AddSeries(Series1);
  Chart1.Align:=alClient;
  For i:=0 to 10 do
    Series1.AddXY(i,Random(100),IntToStr(i));
end;
procedure TForm1.Chart1GetAxisLabel(Sender: TChartAxis;
  Series: TChartSeries; ValueIndex: Integer; var LabelText: String);
  var Value:Integer;
begin
 If ValueIndex<>-1 then
  begin
    If Sender = Chart1.Axes.Bottom then
    begin
            Value := Chart1.Axes.Bottom.CalcXPosValue(ValueIndex);
            If (Value-AntValue>100) and (Value-AntValue<=150) then
              LabelText:= 'XValue'+IntToStr(Value);
        AntValue:=Value;
     end;
    end;
end;

In code you can see values are in determinate range that you can adjust as you want. Please could you tell us if previous code behave as you expected?

I hope will helps.

Thanks,
