Hi Nathan, Thanks for your advice. My line plot is now behaving, and I was able to take advantage of a few other extra options pylab provides. I'm glad that didn't take much! -Noel On Tue, Jul 16, 2013 at 5:51 PM, Nathan Goldbaum <nathan12343@gmail.com>wrote:

Hi Noel,

I would create the ray object and plot by hand, rather than relying on PlotCollection:

pf = load(...) ray = pf.h.ray([0.0, 5.0e9, 5.0e9],[1.e10, 5.0e9, 5.0e9])

data = ray['logden'] t = ray['t']

import pylab pylab.plot(t, data)

Of course you'll need to set your own axes labels this way but it should be a lot more flexible.

Hi yt-users,

I've got another hopefully quick problem I'm looking for help with (thanks for bearing with me with all of my emails!). I'm trying to create a line plot through 'add_ray' in a PlotCollection. It is created just fine, but I can't seem to set the x and y limits of the plot. Neither pc.set_xlim() nor ray.set_xlim() (along with the y-axis versions) do anything. Here is my script:

--------------------- from yt.mods import * pf = load("plt00500")

pc = PlotCollection(pf, 'c') ray = pc.add_ray([0.0, 5.0e9, 5.0e9],[1.e10, 5.0e9, 5.0e9], 'logden')

pc.set_ylim(-5.0, 8.0) pc.set_xlim(0.2, 0.5)

pc.save('ray')

---------------------

But my image remains unchanged: http://i.imgur.com/1jPzHbt.png

What am I missing here? Is it not possible to set the limits on such a plot? Thanks in advance for your help.
