Does PlotGrid require Custom Scaling?

I’m using Amibroker 6.25. Great Update. Thanks!

I want to plot a simple horizontal line across my chart. The line is not visible until I set the properties of PlotGrid (using the Parameters dialog) to use custom scaling, and I set the Minimum and Maximum settings to values below and above my line’s value.

  1. Is this the correct behavior for PlotGrid?
  2. Is there any way to use Automatic Scaling in my formula (because my horizontal line’s value may vary)?
  3. How do I set the scaling properties just for the PlotGrid?

No, you just need at least one Plot() in your formula. Plot() call sets the scale but PlotGrid() doesn’t (it leaves scale unaffected)
