Hello again everyone,
Firstly; due to my questions, this forum is overly busy so thank you to everyone who helped.
I've created SfChart and added a series with checkbox visibility of legend. In addition, I've set primary and secondary axis max min value for series.
My problem is simple: If the combobox status of my series is change (check or uncheck), the startup options of my chart is disappearing (like max min axes value).
Where is the wrong?
