Start of graph being chopped off
Posted: Tue Apr 12, 2005 6:08 am
Hi Guys,
I've been having a problem where the graph does not get drawn completely on a certain brand of laptop. Although it sounds crazy but please bear with me, see both images below:
Normal PC's/Laptops
Problematic Brand of Laptop

Notice that the beginning of the curve gets chopped off. Now I'm showing you this in TeeChartOffice so you have a chance at reproducing it, however we see exactly the same behaviour in the v6 TeeChart control. This problem does not happen all the time, it looks like it happens when it is trying to draw a connecting line between a point outside the visible window to a point that is inside the visible window.
At first I had a hunch that it may have been the operating system that was the problem but I have observed this problem in both Win2000/WinXP in the same brand of laptop and only ever this brand, which is why I suspect the video drivers are somehow triggering this behaviour.
The laptop is a i-Buddie Model:A900i laptop, which is using SiS Video drivers 630/730 latest driver versions

Could you guys try to reproduce the problem there? It is very consistent I have tested this with about 10 of this brand of laptop with varying operating systems. Or any advice or suggestions would be much appreciated.
