You're doing the correct procedure to patch your version.  It doesn't hurt to rerun the install script, but it's unnecessary.  You could have run "python setup.py install" from the yt-hg/ directory instead.<br>

Again on the save(). As I understand YT is set up to be somewhat machine<br>
independent in that all libraries are contained in the YT installation -<br>
in this case the PyX.<br>
I wonder then could there be something in my dev version of YT that is<br>
screwed up.<br>
<br>
Just to confirm what I need to do when I pull down your patch.<br>
<br>
cd .../yt-x86_64/src/yt-hg<br>
hg pull -r 49a5b85 <a href="https://bitbucket.org/jwise77/yt-clean" target="_blank">https://bitbucket.org/jwise77/<u></u>yt-clean</a><br>
hg update<br>
<br>
I then removed the done file and reran the install script. That may not<br>
have been necessary though - I'm not sure.<br>
<br>
Maybe I should try pulling your patch down onto my stable version?<br>

                      Thanks for bringing this to our attention.  I've<br>

                        Plus, it hasn't been updated to be compatible with<br>

                      windows now.  I've tested it with slices,<br>
        projections, off-axis<br>
                      projections, and phase plots, and they now work as<br>

                          Hi All,<br>
<br>
<br>
                          I've been playing with the eps interface a<br>
        little to<br>
                 decorate some<br>
                          plots. It's a very nice feature but I haven't<br>
        been able<br>
                 to get in to<br>
                          work with the output from<br>
        OffAxisProjectionPlot() or<br>
                          off_axis_projection(). Basically I call one of<br>
        these<br>
                 functions,<br>
                          produce<br>
                          a nice projection and would like to pass that<br>
        object to<br>
                          eps.single_plot<br>
                          and make some modifications.<br>
<br>
                          The problem is that PWViewrMPL object has no<br>
        colorbar<br>
                 attribute<br>
                          and so<br>
                          when insert_image_yt() gets called the script<br>
        fails as<br>
                 it tries to<br>
                          access this attribute. I can workaround the<br>
        issue by<br>
                 creating the<br>
                          projection and converting the image to jpg and<br>
        passing<br>
                 the jpg<br>
                          image to<br>
                          insert_image() and it works great but it's not<br>
        very<br>
                 clean. It<br>
                          would be<br>
                          nice to pass the PWViewrMPL object in somehow.<br>
<br>
                          Just wondering if another wrapper function is<br>
        needed or<br>
                 if there<br>
                          is an<br>
                          even easier way that I am missing.<br>
<br>
                          Cheers,<br>
