For example the symbol curve goes from 90 to 100; however the y axis scale shows a 10% gain.

You can't. What you can do is plot (in code) the instrument on a PricePane, like shown in this KB article:

WealthScript Techniques | Relative Performance Chart

I am reviewing the KB article; the chart plane now shows percent from a date.

Is there a way to turn off auto scale and fix the percent start and stop points on the y-axis?

Seeing percent change on a fixed scale would be extremely helpful with building or reviewing strategies, in that as you arrow down through symbols in your data set, the related chart would reflect the percentage gain or loss, without any computation intensive interpolation.

I think this would be a great help.

Thanks

What info do you mean? It's a method with completely revealed code that anybody can modify.

Not exactly. But you can use SetPaneMinMax to fix the upper and lower bounds, provided that the plotted series does not exceed them.

Thank you Eugene and Cone.

SetPaneMinMax looks very interesting. I will try it.

I looked at PlotBenchMarkPct again and I agree it's a method with completely revealed code. I originaly thought it was a wealthscript item.
