Hi Christine, This doesn't fix the underlying issue, but I usually just dump the pngs out with a high dpi and use a conversion from png to eps. If you have Gimp, you may want to give this a shot: http://code.google.com/p/agpy/source/browse/trunk/contributed/pngtoeps?r=247 Others might have better ideas, but my guess is a lot of them will deal with modifying your matplotlib backend, which I've never had great luck with for vector formats.

Hi everyone,
I have a question that may be more of a matplotlib question than a yt question, but it's an issue with some yt generated figures I have, so I thought I'd ask it here. I think there was some discussion of this on the list a while ago but I can't find the thread.
When I output images that include colorbars in vector formats (like pdf and eps), I get these little lines running across the color bar. It goes away if I output the image in a rasterized format (like png). I wanted to output my images in vector format (as pdfs) so everything looks nice and sharp. I've figured out how to just rasterize the color bar. However, I don't want to rasterize the color bar labels, and the way I've implemented it, the labels get rasterized too. It seems in figure objects (and maybe axes objects?) there is a way to specify the order that items get drawn and/or rasterized (through the zorder and rasterized_zorder keywords); I've played around with this but haven't been able to get it to work. The color bar is a Colorbar object and it doesn't seem like this class allows for adjusting the rasterization order of things.
I've pasted an example script here: http://paste.yt-project.org/show/2504/ I'm probably going to give up on this soon, but any advice people have would be greatly appreciated.
Christine
