Bug summary

I'm making many plots in a loop using the same Figure and Axes. The basic setup including a twin Axes is done once and the Axes are cleared at the end of the loop usingcla().

Axes.cla() resets the label position of theyaxis of the twin Axes to the default (left), resulting in misplaced ylabels in all but the first loops.

Ticks and tick labels of the left y axis are kept at the correct side, so I would the axis label also expect to be kept at the correct side.

Code for reproduction

importmatplotlib.pyplotaspltfig,ax1=plt.subplots()ax2=ax1.twinx()foriinrange(2):# do some plotting hereax2.set(ylabel=f'ylabel of plot #{i}',ylim=(1,i+2))fig.savefig(f'{i}.png')ax1.cla()ax2.cla()

Actual outcome

Expected outcome

The expected outcome was produced by addingax2.yaxis.set_label_position('right') to the loop:
