Set Y Axis in OnRender

[TAJTrades]

How can I set the Y axis in OnRender?
Something like: SetYAxis = Highest High of visible bars + (10 * Ticksize.)

chartScale.MaxValue only returns the Y value.

Thanks. Probably something stupidly simple.

Hello TAJTrades,

Thank you for the post.

You must set this parameter through the OnCalculateMinMax method. The help guide page has an example on how to use the method to set the scale for your indicator.

Please let me know if I can assist further.

Bingo, that should work for me.
Thanks Chris, I never saw it in the Help Guide.
