DrawAxisLabel - Formatting

[Heinz]

Hi,

I draw additional labels to the bottom axis using BottomAxis.DrawAxisLabel.

The attached picture shows the labels 200 and 500 added.

Now I want the custom labels to get the same format as the default labels from the bottom axis.
How can I set the properties for the custom labels (f.e. font style, font size, ...)?

Best regards

Heinz

Hi Heinz,

I'm afraid you have to assign the properties you want to the Canvas before calling the DrawAxisLabel method. Something like this:

Code: Select all

procedure TForm1.Chart1AfterDraw(Sender: TObject);
var val: Double;
begin
  val:=250;

  Chart1.Canvas.Font.Style:=Chart1.Axes.Bottom.LabelsFont.Style;
  Chart1.Canvas.Font.Color:=Chart1.Axes.Bottom.LabelsFont.Color;
  Chart1.Canvas.Font.Size:=Chart1.Axes.Bottom.LabelsFont.Size;
  Chart1.Canvas.Font.Name:=Chart1.Axes.Bottom.LabelsFont.Name;

  with Chart1.Axes.Bottom do DrawAxisLabel(CalcXPosValue(val), PosAxis+TickLength+2, 0, FloatToStr(val));
end;

Hello Yeray,

that was the missing link.

Many thanks and best regards
