I’m trying to construct a radar plot for 5 variables. I’ve found the example code (radar_chart.py) for doing this with matplotlib but I’m having trouble adjusting one aspect of the rendering. That sample file produces radar plots with circular frames and ticks (see http://wineinger.me/plotting/radar_chart1.png). That sample code does seem to have an option to use a polygon frame rather than a circle (the default), but this doesn’t seem to do much except erase part of the outer tick lines (http://wineinger.me/plotting/polygon.png vs http://wineinger.me/plotting/circle.png). Plus, I’m looking for the tick lines to parallel the frame, so having a polygon frame with circular ticks would not be useful to me.
Here is an example of what I’d like to produce: http://www.corda.com/docsource/doc7/Manuals/project_graphics/design_graphs_radar_transparency.gif. Can anyone provide some sample code to get me started or at least some direction on how to accomplish this? I’m new to matplotlib though I do have a fair bit of python experience.
