</div>Yes -- if you look at what you're calling, it's "imshow", which<br>
displays it like a bitmap. What yt will do is use pcolormesh, which<br>
actually requires bin edges, so that will give you a better looking<br>
image in that case.<br>
<br>
I think you will be able to get rasterized in as a keyword argument if<br>
you *manually* save your PhasePlot, similar to how the cookbook<br>
examples plot things by grabbing the axes/figure objects on plots.<br>
