Just a (hopefully) quickie - is there an easy way to produce isotropic graph scales.
Cheers,

I think what you are asking for is to have the x and y axis have the same physical scale. This script should do the trick :
// BEGIN SCRIPT
temp=layer.unit;
layer.unit=2;
dx = x2 - x1;
dy = y2 - y1;
if(dx > dy)
{
layer.height = layer.width * dy / dx;
}
else
{
layer.width = layer.height * dx / dy;;
}
layer.unit=temp;
// END SCRIPT

Ok, Here is a data set. In the package that produced it you can select "isotropic scaling" to display a perfect semi-circle. This is needed so that you can spot "distorted" semi-circles. If you plot this in origin is distorts the semi-circle. Hope this helps explain things.

Hi Greadey:
Sorry, we are not familiar to your field. May be "Plot : Multi-Curve : Stack" is what you need?
Could you please provide some sample data and show us an example?
Thanks

Isotropic graph scales produce a perfectly square graph, I am interested since I do alot of electrochemical impedance spectroscopy and isotropic graphs do not distort the semi-circles you obtain with EIS.
Hope this helps :-)

Sorry, I am not very sure about what you mean by "isotropic graph scales."
Would you please explain more or show me an example graph?
