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.

Small update:
I tried the very same code with MPL 1.0.1 and Python 2.5.0 on Linux 64 and
Python 2.5.4 on Win32 and it runs w/o throwing any exceptions there!
But: the behaviour is still not that what I expected. Still these issues are

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 Figure

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 b

With mpl_toolkits.axisartist, it is possible to make an axes of annulus.
But, the resulting axes is not fully compatible with the original
matplotlib axes. Most of the tick-related commands won't work and yo

Is the attached issue with a plain polar axes already fixed? I never

I would like to plot an annulus.
Any pointer would be appreciated.

Hi, I'm new to matplotlib and in need to draw a single impulse on a polar
plot, but don't know how to do it, so i just draw a line using
pylab.polar([0,0],[0,100],'g-')
but when i draw shorter lines or

i get the whole plot filled with green color, instead of a single
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:

Hello,
I've been trying to implement a smith chart like a previous gentlemen on the

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

It seems you're getting bitten by the brain-dead interpolation of points
(which is meant to draw line segments as curves that follow the radii).
I have fixed the polar drawing code in SVN r6106 to normalize theta to
(0.0 <= theta <= 2pi) before doing the interpolation, which seems to fix
your
Hi Tony,
Thank you for the reply, the solutions you propose are fine in this
case. But I'm trying to use the polar plot
as a smith chart for an instrument and there i will receive data that is
unknown but can be something like this:
r = np.transpose(.1+np.arange ( 0 , 0.7 , 0.001))
theta = -4.5
