In fact it does nothing - the value of the argument has no impact on the plot.\r\nTo modify the size of radial tick labels, one must call: ax.yaxis.set_tick_params(labelsize='large')\r\nThis is not obvious.\r\n\r\n\r\n\r\n### Code for reproduction\r\n\r\n```python\r\nimport matplotlib.pyplot as plt\r\nimport numpy as np\r\n\r\n# Make fake data\r\n\r\nd = np.random.rand(11,18)\r\nazimuths = np.radians(np.arange(-42.5,42.6,5))\r\nradials = np.linspace(1.3,3.9,11)\r\nr, theta = np.meshgrid(radials, azimuths)\r\n\r\n# Plot the data\r\n\r\nfig = plt.figure(figsize=(6,6))\r\n\r\nax1 = fig.add_subplot(111,polar=True)\r\n\r\ncont = ax1.contourf(theta, r, np.fliplr(d).T,\r\n                   )\r\n\r\nax1.set_theta_zero_location('N')\r\nax1.set_thetamin(-45)\r\nax1.set_thetamax(45)\r\nax1.set_xticks(np.arange(np.radians(-45),\r\n                        np.radians(46),\r\n                        np.radians(15),\r\n                       ))  # Less radial ticks\r\n\r\n\r\nax1.set_xticklabels(np.arange(-45,46,15)[::-1],\r\n                    fontsize='xx-large',            # This argument controls azimuthal tick labels\r\n                   )\r\n\r\nax1.set_yticklabels(np.arange(-45,46,15)[::-1],\r\n                    fontsize='xx-large',            # So why does this not control the radial tick labels?\r\n                   )\r\n\r\n# ax1.yaxis.set_tick_params(labelsize='xx-large')      # Especially when this line *does* control them\r\n\r\nplt.show()\r\n```\r\n\r\n\r\n### Actual outcome\r\n\r\nHere you can see that the radial tick labels are too small, unaffected by the set_yticklabels command:\r\n\r\n![download](https://user-images.githubusercontent.com/47150532/148107999-89de7288-5491-4690-998e-8b4b90dbfe48.png)\r\n\r\n\r\n### Expected outcome\r\n\r\nThey should be this size.
