inset_axes and polar plots

Hi everybody,

I’m trying to insert polar axes into another axis. I need to place many windrose-like plots (bar plots in a polar axis) inside an xy plot. I need them to move while panning the xy plot. To do so, I tried with inset_axes, but I cannot force the new axis to be polar.

Or is there a better way to to it ?

Here is the code:



import matplotlib.pyplot as plt

import numpy as np

import mpl_toolkits.axes_grid1.inset_locator as iloc

angleStart = 0.75

angleEnd = 2.5

ringOutterLimit = 0.95

ringWidth = 0.4

lineWidth = 1

values = np.array([0., 0.3, 0.95, 0.5, 0.1])

Figure and main axis

fig = plt.figure(figsize=(5,5))

ax1 = fig.add_subplot(111)

ax1.plot([0,1], [0,1])


Second axis

ax2 = iloc.inset_axes(ax1, width=“100%”, height=“100%”, loc=3,

bbox_to_anchor=(0.3, 0.5, 0.1, 0.1),


bars =[np.pi/2., np.pi], [0.5, 0.2], width=.1*np.pi)

Third axis

ax3 = iloc.inset_axes(ax1, width=“100%”, height=“100%”, loc=3,

bbox_to_anchor=(0.5, 0.7, 0.1, 0.1),


bars =[np.pi/2., np.pi/4.], [0.1, 0.4], width=.1*np.pi)

Thanks a lot,
