3D plots gained a 3rd "roll" viewing angle#

3D plots can now be viewed from any orientation with the addition of a 3rd roll angle, which rotates the plot about the viewing axis. Interactive rotation using the mouse still only controls elevation and azimuth, meaning that this feature is relevant to users who create more complex camera angles programmatically. The default roll angle of 0 is backwards-compatible with existing 3D plots.

from mpl_toolkits.mplot3d import axes3d
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(projection='3d')
X, Y, Z = axes3d.get_test_data(0.05)
ax.plot_wireframe(X, Y, Z, rstride=10, cstride=10)
ax.view_init(elev=0, azim=0, roll=30)
