1. Currently there is no option to change the font of the texts.
2 I suppose you are speaking of this:

The problem is the right to left text. This not taken into account.

3. I need to look further for that.
How do you refresh and recall the chart.
Could you post a small project as a zip file showing this problem.

I had a look at your project.
The problem with the zoom is that in BarChart1.SetZoomIndexes(2, DataCount)
DataCount is heigher than the number max of points !
With BarChart1.SetZoomIndexes(2, DataCount - 1) it works as you expect it.
I added a check for values out of the limits.
Attached the modified version.
