Hi all,
I am trying to create a simple slice plot for the central 1 pc of a simulation box of size  1 mpc using the following  simplest script.  Problem occurs when I set plot width  as can be seen in attached plot.  I tried stable version of yt as well development fork but did not get any success. Slice  works well without any problem if I use pc.add_slice method.  Any ideas what is going wrong here.
thanks in advance,

(pf, 'x', "Density", width = (800.0, 'kpc')).save()
