[yt-users] xstick label in yt slice plot

[Nathan Goldbaum]

Hi Yanfei,

So I looked a little closer at the code. It looks like the 'domain' origin
sets the origin of the plot at the lower-left-hand corner of the *domain*,
which for your dataset is *not* the same thing as setting the origin of the
plot at the origin of the simulation's coordinate system.

What you want is to set the origin to 'native', which sets the origin to be
the same as the origin of the simulation coordinate system. Here is an
example with that choice:

Hope that's helpful,

Nathan
