Trying to set_ylim(bottom=0) on a log scaled axis changes plot #7733
Description
import matplotlib.pyplot as plt
fig, axs = plt.subplots(2, 1)
axs[0].scatter(range(0, 4), [0, 1, 2, 3])
axs[1].scatter(range(0, 4), [0, 1, 2, 3])
axs[0].set_yscale('log')
axs[1].set_yscale('log')
axs[1].set_ylim(bottom=0)
plt.show()This raises
/home/dstansby/matplotlib/lib/matplotlib/axes/_base.py:3174: UserWarning: Attempted to set non-positive ylimits for log-scale axis; invalid limits will be ignored.
'Attempted to set non-positive ylimits for log-scale axis; '
However, the 2nd plot is changed by the set_ylim(bottom=0) call, and no data is visible.
