I assume you are getting the white where the field is zero? If you are using a color bar with black as the color for the lowest value (like 'gray’), this will give you black where the field you are projecting is zero (or rather tinny-tiny).<div><br></div><div>Christine</div><div><br><div><div>On May 28, 2014, at 2:51 PM, Nathan Goldbaum <<a href="mailto:nathan12343@gmail.com">nathan12343@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;"><div dir="ltr">Hi Andrew,<div class="gmail_extra"><br><div class="gmail_quote">On Wed, May 28, 2014 at 1:12 PM, Andrew James Emerick<span class="Apple-converted-space"> </span><span dir="ltr"><<a href="mailto:emerick@astro.columbia.edu" target="_blank">emerick@astro.columbia.edu</a>></span><span class="Apple-converted-space"> </span>wrote:<br><blockquote class="gmail_quote" style="margin: 0px 0px 0px 0.8ex; border-left-width: 1px; border-left-color: rgb(204, 204, 204); border-left-style: solid; padding-left: 1ex;"><div dir="ltr">Is there a way to set the background color for projection plots?

The first is to pass the 'facecolor' keyword argument down to matplotlib when calling the save function. Unfortunately since the foreground is black by default, you'll also have to adjust the colors of all of the axes, tick marks, axes text, colorbars, etc to be white. Here is an example notebook that does this: <a href="http://nbviewer.ipython.org/gist/ngoldbaum/7367380cbe6683159da5">http://nbviewer.ipython.org/gist/ngoldbaum/7367380cbe6683159da5</a></div><div><br></div><div>Another option would be to adjust the matplotlib defaults in your matplotlibrc (<a href="http://matplotlib.org/1.3.1/users/customizing.html">http://matplotlib.org/1.3.1/users/customizing.html</a>) so that figures have a black background by default.</div><div><br></div><div>I have to say that I kind of like the way the black background looks and could definitely see it being useful in some situations. I don't think it would be very hard to add a "set_black_theme" function that does more or less what my notebook does. That would probably be a nice afternoon hack for someone that wanted to familiarize themselves with yt's plotting code.</div><div><br></div><div>Hope that's helpful,</div><div><br></div><div>Nathan</div><div> </div><blockquote class="gmail_quote" style="margin: 0px 0px 0px 0.8ex; border-left-width: 1px; border-left-color: rgb(204, 204, 204); border-left-style: solid; padding-left: 1ex;"><div dir="ltr"><div><br></div><div><br></div><div><br></div><div>Thanks,</div><div>Andrew E.<span class=""><font color="#888888"><br>--<span class="Apple-converted-space"> </span><br><div dir="ltr"><div style="font-family: arial; font-size: small;">Graduate Student </div><div style="font-family: arial; font-size: small;">Columbia University</div><div style="font-family: arial; font-size: small;">Department of Astronomy</div></div></font></span></div></div><br>_______________________________________________<br>yt-users mailing list<br><a href="mailto:yt-users@lists.spacepope.org">yt-users@lists.spacepope.org</a><br><a href="http://lists.spacepope.org/listinfo.cgi/yt-users-spacepope.org" target="_blank">http://lists.spacepope.org/listinfo.cgi/yt-users-spacepope.org</a><br><br></blockquote></div><br></div></div>_______________________________________________<br>yt-users mailing list<br><a href="mailto:yt-users@lists.spacepope.org">yt-users@lists.spacepope.org</a><br><a href="http://lists.spacepope.org/listinfo.cgi/yt-users-spacepope.org">http://lists.spacepope.org/listinfo.cgi/yt-users-spacepope.org</a></div></blockquote></div><br></div></body></html>
