Hi Ken,
I am afraid, multiple scales on Y axis cannot be implemented directly, instead you can implement multiple axes through which data points of various scales can be plotted in a chartControl.
Please refer the attached sample that implements this using multiple axes. I hope i have not misunderstood what you are asking. If i have, could you please brief me more about your requirements? This will help me bring out a better solution.
Thanks for your interest in Syncfusion products.
Regards,
Geetha
