Line Chart, a way to have to Zero line on the Y-axis in <

[HLEBOEUF]

Is there a way, in a line-chart with chart-lines-values going between -50 and +50 to have the 0 (zero) line a bit ticker.
Now there are several line on the Y axis (wich is good) but the zero line should (in my case) be easy to see.

Thx

Hi HLEBOEUF,

Yes, you could do implement how do you want to display the zero label at the GetAxisLabel event doing something like:

Code: Select all

procedure TForm1.Chart1GetAxisLabel(Sender: TChartAxis;
  Series: TChartSeries; ValueIndex: Integer; var LabelText: String);
var
  SpecialLabel: String;
begin
  SpecialLabel:='0';
  if ((StrComp(PChar(LabelText),PChar(SpecialLabel))=0) and
      (Sender=Series1.GetVertAxis)) then
    With Sender.LabelsFont do
    begin
      Style:=[fsBold];
      Size:=10;
      Color:=clRed;
    end
  else
    With Sender.LabelsFont do
    begin
      Style:=[fsItalic];
      Size:=8;
      Color:=clBlack;
    end;
end;

You could also use Custom Labels or a Color Line Tool. For more information on those options please have a look at the TeeChart features demo, available at the TeeChart program group and search for those terms.
