[yt-users] problem with zoom slice plot

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