I just finished another TAChart tutorial. This one demonstrates how to
create a chart with two y axes.

Excellent, thank you.
I did some proofreading and minor corrections.

Some notes:
1) It is possible to achieve the "50 M" marks on the left axis by
using Marks.Format
instead of OnGetMarkText. I understand that you wanted to demonstrate
the latter,
but the former should at least be mentioned as a simpler alternative.
2) I am not sure, but may be "legend" should be present in the title?
3) Perhaps it would be useful to create "TAChart Tutorial" category?
