Thanks. I did figure that out. Unfortunately there are more issue I am facing. One is that apparently you can't set the Chart Scale at run time. It appears that the chart capability while perhaps very useful for many applications, for what I am doing it may not be flexible enough.
The charts I am creating are Line charts that analytical result values vs dates. I need to set the scale based upon a Standard Deviation and draw lines across for + 2SD and - 2SD. Does not appear that this is doable/
