Hi,

Hopefully somebody can help me shed some light on this...

I have a DBChart (Actually it really doesn't matter I have same problem with TChart).

In this chart I have a TLineSeries beginning with a couple of null values - I dont want to show/paint these null values so I am using "LineSeries.TreatNulls := tnSkip;"

This works ok - Except for the beginning op the graph which is random! This gives a random straight line on my chart

To narrow down my problem and reproduce it, I tried to save to a tee file and loading it in a standard TChart = same problem. (Maybe not at initial load - but do a resize and the error reproduces consistently!).

I have included the .tee in the bottom of post if someone wants to see for them selves...

Any help on this matter would be greatly appreciated.

Regards
Christian
