Clipping of LineSeries

Post by Heinz » Mon Jan 25, 2010 11:20 am

Hi,

having LineSeries the datapoints with Y-values lower than LeftAxis.Minimum are not shown:

But switching to 3D-view the datapoints with Y-values lower than LeftAxis.Minimum are visible:

3D.JPG (48.84 KiB) Viewed 4325 times
Is there a possibility to make these points unvisible in 3D-view?

Best regards

Hi Heinz,

I'm afraid not. This is a known issue in the wish-list (TV52013260) which we will try to enhance for future releases. It's not an easy one though. It will probably involve important series painting redesign.

Hi Heinz,

As an update, a workaround could be using null points to hide the ones out of the axis range. Something like following:

Code: Select all

procedure TForm1.Button1Click(Sender: TObject);
var i: Integer;
begin
  Series1.TreatNulls:=tnDontPaint;
  Series1.IgnoreNulls:=false;
  for i := 0 to Series1.Count-1 do
  begin
    if Series1.YValue[i] < Chart1.Axes.Left.Minimum then Series1.SetNull(i)
    else Series1.SetNull(i,false);
  end;
end;

Hi Narcis & Yeray,

many thanks for your answers.
In the meantime I also found a workaround by setting the valuecolor-property for these points to clNone.

Best regards

Hi Heinz,

That's what null points do internally ;)
