Missing scale

Bug summary

The scale on the y-axis is missing in some logarithmic plots.

Code for reproduction:

import matplotlib.pyplot as plt

x = [1, 2]
y = [3.7, 3.8]

plt.plot(x,y)
plt.yscale("log")
plt.show()

Actual outcome

Expected outcome

There should be a scale on the y-axis. Without the scale, you can't tell what the value of y is.

Matplotlib version

Thanks for reporting this - I think its a duplicate of #8768, and is being handled by #12865, so it should be fixed soon. In the meantime, you can change the locator to AutoLocator for such a small dynamic range: https://matplotlib.org/examples/ticks_and_spines/tick-locators.html

I'm going to close, but feel free to comment at #12865 if you think your issue is different.
