Tchart 8, Delphi 6,

Am using series.addnullxy(x,y) to add null points to a series. I want the series to draw points at valid non-null x,y, with lines connecting the non-null points. But where there is a null I want a gap in the lines connecting the non-null points. However, I'm getting a line between the point before the null to the point afterhte null.

Any ideas what to set please?

cheers
Sean

Hi Sean,

I'm not able to reproduce the problem here. It works fine for me using the code below. This code doesn't paint a line from 3 to 5. Could you please test if the code work fine at your end and modify it so that we can reproduce the problem here?

Code: Select all

  With Series1 do
  begin
    AddXY(1, random);
    AddXY(2, random);
    AddXY(3, random);
    AddNullXY(4, random);
    AddXY(5, random);
    AddXY(6, random);
    AddXY(7, random);
  end;

Thanks in advance!
