xy radar chart

Short but useless answer: I'm sure it is possible in Excel. It might be easier in some other graphing application, but I expect it is possible.

To get any more specific than that, you will probably have to explain in more detain exactly what you want.

My first thought for a "scatter in radar chart" is that you are looking for a "polar chart" or something that uses polar coordinates for charting. Along those lines, I suggest reviewing Andy Pope's discussion and examples for polar plots. http://andypope.info/charts/polarplot2.htm I expect that, once you figure out how to convert your data to "angle" and "distance", the techniques he describes should allow you to build the desired chart.
