How to plot straight lines on polar plots

Thanks for the help, but I can't quite see where to add the add_axes code.
Here is the code I have been using to plot, the polar plot is a subplot.

ax=fig.add_subplot(111, polar=True)

Change this to

  ax=fig.add_subplot(111, polar=True, resolution=1)

and the resolution will get passed to the PolarAxes instance.

What version of mpl are you using? This should be fixed for releases >= 0.98.4
