python - Move radial tick labels on a polar plot in matplotlib -

from matplotlib examples:

import numpy np import seaborn sbs import matplotlib.pyplot plt  r = np.arange(0, 3.0, 0.01) theta = 2 * np.pi * r  ax = plt.subplot(111, polar=true) ax.plot(theta, r, color='r', linewidth=3) ax.set_rmax(2.0) ax.grid(true)  ax.set_title("a line plot on polar axis", va='bottom') plt.show() 

how move radial tick labels (0.5, 1.0, 1.5, 2.0) different angle, 120 deg?

with version 1.4 or later, can use "set_rlabel_position". e.g. place radial ticks long line at, say, 135 degrees:

ax.set_rlabel_position(135) 

the relevant documentation residing here, bit hidden under "projections".

adding line above yields (i don't have seaborn has default matplotlib formatting):

prior 1.4, ax.set_rgrids can take angle argument.
