Hi Reda,

The AutoRange algorithm has to decide on a range if there is only one data-point. I don’t know the algorithm off the top of my head but different users have different requirements. As soon as you add two or more points it will become much more stable. The algorithm to choose AutoRange for 2+ points is to include Min-Max and any AxisBase.GrowBy (padding) factor.

I’m afraid this is a limitation of any charting engine, but if you want fine-grained control over the VisibleRange during re-draw, you can try using the ViewportManager feature.

Hope this helps,
Andrew
