Simplest way to force a scale

[giogio1]

This test indicator plots a line in the panel 2 at value 0 (just as example)
but I cannot get it to show it in the middle of the panel so I can better see it.
Sometimes I just need a dotted Line where the color at each bars changes.
What's the simplest way to place it in the middle of the panel 2?
Thank you

Hello giogio1,

Thanks for your post.

To center the plot within the Y-axis of the panel containing the plot, you could set ChartScale.Properties.YAxisRangeType to YAxisRangeType.Fixed in OnRender() and set the maximum and minimum value for the Y-axis scale using ChartScale.Properties.FixedScaleMax and ChartScale.Properties.FixedScaleMin.

See the attached example script demonstrating this.

Also, see the help guide documentation below for more information and sample code.
