Fix matplotlib call (#434)

### What kind of change does this PR introduce?

* Fixes a `matplotlib` for v3.10+ compatibility.
* Pins `pygments` to avoid a breaking change affecting
`sphinx-codeautolink`

### Does this PR introduce a breaking change?

No.

### Other information:

It's not entirely clear to me whether the dual histograms are being
drawn properly to begin with. Alpha values from `ax` are the only ones
that seem to matter when examining the graphic generated during tests.
