Automatically scaling a Custom render

[swcooke]

I have created a custom render that draws a line between 0 and 1 as a test. Is there any way to set the scale automatically when the Indicator loads? How do I set these things from inside my NinjaScript?

If I am on the wrong track, please let me know. My goal is for it to automatically scale with a little space on each side of the value that is rendered. What is a common approach to doing this?

Hello swcooke,

Thanks for opening the thread.

AutoScaling will have to be enabled for the indicator doing the custom drawing, and the indicator must also use OnCalculateMinMax() to update MinValue and MaxValue based on your custom rendering points and some offset.

OnCalculateMinMax() is documented here - https://ninjatrader.com/support/help...lateminmax.htm

Please let us know if you have any additional questions.
