I have been able to master the plotting of XY, XYY, XnY plots using the threesin forum workthrough (see reply at http://software.intel.com/en-us/forums/showpost.php?p=34300

However, I do not understand how the transform, position, origin, and size methods and properties work on a specific graph area. The general discussion on transforms is a bit simplistic, I understand the graph window goes from -1,-1 to +1,+1 but that helps little. I have used various plots in AViewer and understand the approximate ideas of origin and size, ie, size things about 15% larger than your largest data so you have some margin to operate for axes, labels etc. I would like to see a better diagram of what the transform does.

I wish to scale my XnY plots so that the maximum Y series fits on the graph. Inheriting transform data from previous y-data doesn't help since you don't know which series is the biggest. I could examine all my data beforehand, decide which is largest and use that as my first series, but that will mess up other features of the plotting. I am sure there is a slick solution out there.

Thanks in advance.
