matplotlib.axis.XAxis.remove

XAxis.remove()

Remove the artist from the figure if possible. The effect will not be visible until the figure is redrawn, e.g., with matplotlib.axes.Axes.draw_idle(). Call matplotlib.axes.Axes.relim() to update the axes limits if desired.

Note: relim() will not see collections even if the collection was added to axes with autolim = True.

Note: there is no support for removing the artist's legend entry.
