Hi Dan, Callbacks are run in the order they are called. That said, even if you run the callbacks in the correct order, you will still see a circle on top of the contours due to the way matplotlib handles things that need to be drawn on top of other things. The way to fix this is to pass "zorder" to matplotlib. Here's an example using a public dataset from yt-project.org/data: import yt ds = yt.load('IsolatedGalaxy/galaxy0030/galaxy0030') plot = yt.SlicePlot(ds, 2, 'density') plot.annotate_contour('density', plot_args={'zorder': 1}) plot.annotate_sphere(ds.domain_center, (100, 'kpc'), circle_args={'color': 'white', 'zorder': 2}) Here "plot_args" and "circle_args" are passed directly to matplotlib, so they allow you to pass keyword arguments to matplotlib's drawing functions that wouldn't otherwise get passed in by yt. Hope that's helpful, Nathan On Mon, May 16, 2016 at 1:40 PM, Daniel Fenn <dsfenn@gmail.com> wrote:

Hi,

Is it possible to control the order that plot annotations are drawn? For example, right now I'm plotting density contours, and I'd like to add a circle annotation on top. However, when I add the circle, it's drawn behind the density contours. This happens no matter the order that I add the annotations in my script.

Is there a straightforward way to force the circle to be drawn on top of the density contours, so that it's not obscured?

Thanks,

Dan
