Hi Matt,
Thank you for the work on colorbar! And you mean I can plot a slice with mapserver at a specific position, right?
I typed: yt mapserver -h
===================================================
usage: yt mapserver [-h] [-p] [-f FIELD] [-g WEIGHT] [-a AXIS] [-o HOST]
pf [pf ...]
Serve a plot in a GMaps-style interface
positional arguments:
pf Parameter files to run on
optional arguments:
-h, --help show this help message and exit
-p, --projection Use a projection rather than a slice
-f FIELD, --field FIELD
Field to color by
-g WEIGHT, --weight WEIGHT
Field to weight projections with
-a AXIS, --axis AXIS Axis (4 for all three)
-o HOST, --host HOST IP Address to bind on
===========================================
I'm not sure with which option I could give specific coordinates.
Thanks again,
Jia-Hung

Hi Jia-Hung,
Glad it worked for you!
Colorbars are somewhat tricky because they require global knowledge, but each tile is generated independently. Ben Keller, Sam Skillman and Nathan Goldbaum were working on a widget for IPython that would provide something like htat. For specific positions, you should be able to specify the coordinate of a slice, but it's not possible right now to do it more generally during the course of the exploration.
--help should describe how to make projections, change coordinate of slice, etc etc.
