Break in the line for FastLine chart

In some cases the data that I am working with on a FastLine chart will have NULL values for the limits in the database. I would like to have a break in the line when those values are NULL rather than a line drawing from the last non-null value to the next non-null value. Is there a setting that I can use to force that to happen?

Hi KingDesigns,
I think that you are looking for this:
Code: Select all
TChart1.Series(0).asFastLine.IgnoreNulls = False
TChart1.Series(0).asFastLine.TreatNulls = tnDontPaint
Otherwise, please, take a look at the demo at

I am thinking that those properties are in the newer version. I am using version 7 and they are not available. Is there a way do this for v7?

Hi KingDesigns,
In v7 the property TreatNulls doesn't exist, but you can set IgnoreNulls as false and they shouldn't be displayed. As a simple example, this works fine for me with TeeChart ActiveX v7.0.1.4.
Code: Select all
Private Sub Form_Load()
TChart1.Aspect.View3D = False
TChart1.AddSeries scFastLine
TChart1.Series(0).FillSampleValues 25
TChart1.Series(0).SetNull 5
TChart1.Series(0).asFastLine.IgnoreNulls = False
End Sub
