Hi Michael,
I created the closest corresponding DIAdem polar plot to your posted picture. The bad news is that DIAdem polar plots do not support the spider web display of your attached picture, nor standard marker shapes at each point (but it does support arbitrary keyboard characters as markers). I think the lower case "o" character looks reasonable, though. I also had to create the UserCommand "PolarLabels()" located in the "Polar Labels.VBS" in order to show the point index along the outside of the polar plot.
The good news is that I also included a VBScript which automatically reads off the maxima from the numeric channels in each desired Group and dynamically creates the "Angle" and "Maxima" channels for each Group, as well as automatically setting the number of sectors in the polar plot to the number of maxima.
The attache ZIP file has two REPORT layouts in it. The "Polar Maxima1.TDR" file is a standard layout with one curve configuration for each displayed curve on the polar plot. It has the advantage that the "o" symbol can be the same color as the curve it belongs to, and you can specifically choose which Groups to show a maxima curve from. The "Polar Maxima2.TDR" file is a "name-expansion" layout with only one curve configuration that will show N curves. This is useful if you don't know ahead of time how many curves you'll need to show on the same graph. The disadvantage is that it will always show all the Group curves, the chanels it shows all have to have the same names, and the markers from all curves have to have the same color.
