Scale Properties of additional panels

[Berry Trader]

I'm building some oscillating indicator and want to keep a zeroline centered vertically on the panel. If the indicator, such as MACD or ROC as had a big move in one direction, the zero line does not stay centered. I think this is a feature - so that when you press the "F" focus button, the indicator lines take up most of the panel. I have set the scale properties to fixed an entered the same number (positive) for the top and (negative) for the bottom of the scale. This means I have to manually adjust the scale by dragging while trying to trade. Is there a better solution? Can the scale properties be addressed programmatically?

Thanks for helping me think about how to solve this issue.

Hello Berry Trader,

You could add an indicator with code to set the MaxValue and MinValue in OnCalculateMinMax().

Disable AutoScale all other indicators and data series and the one indicator would control the range and scale of the chart.

This sounds elegant. I'm eager to try it out. Thanks!
