PR summary

I have added a test for Axes.hist2d in lib/matplotlib/tests/test_datetime.py that tests with randomly created data if the data correctly plots. It is similar to the Axes.hist method of testing, as it uses similar generated data and methods.

This addresses the Axes.hist2d task from #26864.

Below is a picture of the generated plots.

If you want to use randomness, you'll need to set a seed (we use 19680801 for tests).

This fits in one line, AFAICT.

I don't see what the difference is between the first plot and these two?

To possibly clarify a bit: it would make more sense to use dates for the y-values as well. So one idea is to keep one of the subplots, swap x and y values for the next (dates on y-axis) and let the third have dates for both x and y-values.

date2num means you are passing numbers into hist2d. We want to test actual dates.
