Thank you for noting that, I did not think to checkxmin/xmax as dates here - I have updated this test to do so, both with singular datetime values and datetime arrays.

This is what the plot generated by this example code looks like:

I added singular float arguments for xmin/xmax - I think that might be why one of the CodeCov checks did not pass.

Here is what the new plot looks like:

@ksunden@scottshambaugh could I please have some advice on why the codecov/project/tests check is not passing? It's at 98.76% "compared toa589856" - I don't know why it's comparing this to the test for scatter.

If anybody is having the same issue, I think it stemmed simply from the fact that my branch was not current with the main body of work. Synchronizing it fixed the issue.
