I am using a workaround now. But that is a hackery solution.
Before plotting my data I convert it to dBs and limit it to the lowest value
I want to display. Then I plot it using a regular polar plot with a custom
formatting function that sets the tick labels with respect to the data
offset.
Ben,
I should have mentioned that I already tried that. When I set the rscale to
'log' the plot crashes when zooming or mpl cannot even create it.
Maybe some example code will help:
from numpy import arange, sin, pi, cos, ones
from matplotlib.backends.backend_tkagg import

I tried the very same code with MPL 1.0.1 and Python 2.5.0 on Linux 64 and

But: the behaviour is still not that what I expected. Still these issues are
remaining:

Hi,
I am trying to display some complex values in a polar plot. Displaying
linear magnitude vs. angle - of course - works without any issues. But I'd
rather display the logarithmic magnitute vs. angle. Since the data for the
radius gets negative then, it'll be wrapped around / rotated by 180deg

Yeah, it's my issue, but I'm not happy with fixing it. Currently,
matplotlib forces the xticks (i.e., the theta ticks) to be at sensible
values via .set_xticks() and .set_xlabels() (projections/polar.py).

Hi all,
Is it possible to create a polar plot, where the lower
bound of the radius is larger than zero ?
I would like to plot an annulus.
Any pointer would be appreciated.
Thanks in advance

With mpl_toolkits.axisartist, it is possible to make an axes of annulus.
But, the resulting axes is not fully compatible with the original

The grid line will reappear if you set high enough resolution.
plt.subplot(111, polar=True, resolution=100)
This should be filed as a bug, though.
I guess the current default for resolution is 1. I think this was to
enable to draw a straight line in polar projection. However, my guess
is that it
Hello,
in version 0.98.5.2 the polar plot still has a problem with negativ angles.
The polarplot is drawing a circle when the angle changes from negativ to
positiv (e.g. from -0.01 to +0.01).
But in What new in 0.98.4
(http://matplotlib.sourceforge.net/users/whats_new.html) I can read:

Hi All -
is there any way to make a polar plot with the center of the plot
*not* set to 0? I tried resetting ylim, but that just changes the grid
laid over the plot, not the location of the markers.

Thank you for the reply, the solutions you propose are fine in this
case. But I'm trying to use the polar plot

unknown but can be something like this:
