Use ax.add_image rather than ax.images.append in NonUniformImage example

anntzer · anntzer · commit 42fe71e6fd37 · 2020-10-14T14:48:23.000+02:00
add_image sets up a few additional things on the artist (it makes
`remove()` work and generates a label), and avoids directly manipulating
the `.images` attribute, which may become read-only in the future.
