Re: [yt-users] p.modify["point"]

5 Oct 2012

      Hi Elizabeth,

There was a bug in the point callback - thanks for pointing it out. I 
noticed another spot in the arrow callback that could cause issues in 
the future for the same reason and fixed that one too.  I've pushed the 
fixes in b8175a113d8e.

Hi Nathan,
Any image creation that uses point should do it. e.g.
from yt.mods import *
pf = load("DD0200/GT_BTAccel_256AMR4_PeHeat_sf5_SNe_0200")
pc = PlotCollection(pf, center=na.array([16.0, 16.0, 16.0]))
p = pc.add_projection("Density", 2)
p.modify["point"](na.array([18.0, 16.0, 18.0]), "hello!")
pc.save()
which gives error:

Hi Elizabeth,
Sorry to hear you're having trouble.  This is likely due to changes I had to make the plot modifications so that they work correctly with the new plot window plots.  I'm trying to reproduce the error.
It would help to see the a shortened version of the script you're running that reproduces the incorrect behavior?  Also, was the TypeError at the end of the traceback the full error or did it get cut off when you pasted it into the e-mail?
Thanks,
Nathan

Hi,
The error with p.modify["point"] seems to have reappeared with the latest version of yt.
It complains when you set the width, or save, but the problem only occurs when marker["point"] is being used.
