X Axis display K(kilo), M(Mega) ,G(Giga) T(Terra)

How to write the BottomAxis->AxisValuesFormat so it can display:
ex: 1200 to 1.2K, 15000 to 15K, 2500000 to 2.5M, etc

Hi Herman,

You need to do it manually in TChart's GetAxisLabel event. A similar example would be:

Code: Select all

procedure TForm1.Chart1GetAxisLabel(Sender: TChartAxis;
  Series: TChartSeries; ValueIndex: Integer; var LabelText: String);
begin
var tmp : Double;
begin
    if Sender = Char1.Axes.Bottom then
    begin
        tmp := StrToFloat(LabelText);
        tmp := 1.0 - 1.0/(Exp(Exp(tmp)));
        LabelText:=FormatFloat(Chart.LeftAxis.AxisValuesFormat,tmp);
    end;
end;
