[yt-users] PlotCollection

[Junhwan Choi (최준환)]

Hi Nathan,

Thank you for your advice.
I try to replace PlotCollection to SlicePlot and I got error.
I find that I have to pass the normal vector and field name when I
call the SlicePlot/ProjectionPlot from the beginning unlike the
PlotCollection..
It looks like that it limit the SlicePlot get only one perspective at
once in the multi plot.
[Am I correct?]
However, as you see my script, I would like to show three different
perspective at once and it was done by add_slice to PlotCollection
previously.
In addition, if this is the case, I cannot make multi plot mixed with
slice and projection.
It looks like that replacing  the PlotCollection  simply SlicePlot and
ProjectionPlot limit the potability of yt…..
There should be other way to go…..

Thank you,
Junhwan
