Hi Junhwan,<br>
<br>
We're still working some of the kinks out, but I think you will be<br>
able to get what you are looking for by projecting the field<br>
("deposit", "all_density") . This would look like:<br>
<br>
pc = ProjectionPlot(pf, "x", ("deposit","all_density"), width = (1.0, 'mpccm'))<br>
