Hi-- Is there a non-callback way to add plot titles to things like profiles? d.
Hi Dave, I believe that you should be okay directly modifying the _axes object of the plot, if you are modifying profile plots. This is probably not the case for slices and projections, if you change the image viewing width. You could accomplish this by something like: plot = pc.add_phase_sphere(...) plot._axes.title("My Title") You can also access the figure with _figure. The callback interface is something of a pragmatic approach to the system of plotting used for variable mesh plots -- slices, projections, etc. The idea was that one should be able to overlay a set of data-oriented modifications to the plot, because for a given plot, multiple images might get saved, for instance at different widths. So I set up a system of "callbacks" designed such that every time the plot was erased and recreated, it would have (laid on top) the same contours, or velocity, but changed the same way the image had been changed. So for a "Density" zoomin, you'd only have to add the "Temperature" contours once, and every time you changed the width they would be updated. Because the variable mesh plots have their axes wiped between updates of the image data, all the other data plotted on those axes are wiped as well. That's why the callbacks are necessary for things like simple annotations. The long term strategy for the callbacks is to provide a much simpler interface for very simple things. I hope to implement this very soon. -Matt On Mon, Jun 15, 2009 at 4:41 PM, david collins<antpuncher@gmail.com> wrote:

plot = pc.add_phase_sphere(...) plot._axes.title("My Title")
This was the first thing that I tried, but it looks like the title field gets wiped during the save. I did
pf = MyOutputs.FileStaticOutput(file) pc = raven.PlotCollection(pf) region = pf.h.region([0.5]*3,[0.0]*3,[1.0]*3) profile = pc.add_profile_object(region,['Density','VolumeFraction']) profile._axes.set_title('Bacon Hat Density') print profile._axes.title Text(1,1,'Bacon Hat Density') pc.save('stuff.png') print profile._axes.title Text(1,1,'')
and there's no title on the resulting plot. Is there something obviously dumb with the above, aside from the plot title? I can make a callback that does it, and it works fine, though-- for those of you following along, I did class title(raven.PlotCallback): def __init__(self, title="Plot"): self.title = title def __call__(self,plot): plot._axes.set_title(self.title) profile.add_callback(dave_callback.title(title)) d.

Hi Dave, I have added this to the trunk repository and yt-1.5. Incidentally, the invocation of callbacks has become much simpler (and I am in the midst of documenting this, but this particular section is already online: http://yt.enzotools.org/doc/howto/quick_plots.html#plot-modification ) and you can invoke them by using the "modify" attribute: profile = pc.add_profile_object(...) profile.modify["title"]("MyPlot") is the shorter and more straightforward way. I would encourage you not to use the manual add_callback method, as it's clunky and ugly and I regret setting it up that way in the first place. -Matt On Tue, Jun 16, 2009 at 11:44 AM, David Collins<dcollins@physics.ucsd.edu> wrote:
