[yt-users] eps_writer question

[John Wise]

Hi Junhwan,

Sorry for the delayed response and the lack of documentation. 
multiplot_yt isn't working for you because you're overwriting the 
PlotCollection for each output.  Plus, PlotCollections are designed to 
work on an individual output.

There are two ways to use eps_writer with different outputs.

1. Write the images to disk, convert them to JPEG, and include them in 
the figure.  I've uploaded the script that generated Figure 1 in

http://arxiv.org/pdf/1011.2632.pdf

to

http://paste.yt-project.org/show/3135/

2. Extract the plots from the PlotCollection into a list of plots.  Then 
eps_writer can accept this list in the argument "yt_plots".  I've 
uploaded an example to

http://paste.yt-project.org/show/3135/

that generated Figure 5 in this paper

http://arxiv.org/pdf/1206.1043.pdf

I hope these examples clears things up, and let me know if this works 
for you.

Cheers,
John
