Hi, The error with p.modify["point"] seems to have reappeared with the latest version of yt. It complains when you set the width, or save, but the problem only occurs when marker["point"] is being used.

Hi Matt,
Thanks! That fixed it.

Hi Elizabeth,
Okay, that helps -- I've pushed a fix. Hash dab58ec7b5e2.

This is the full error spiel. If I comment out the point line, then it's fine.

Hi Matt,
No, the marker works fine. By itself, it is no problem.

Hi Elizabeth,
It looks like the error might be in marker (But it's tough to tell from the one error) so maybe try:
p.modify["marker"](t1clouds[c]['position'], plot_args = dict(marker = 'o')

Hi,
I'm trying to add text to a particular point in my slice. I've got:
position = na.array([20.2, 13.8, 16.0]) pc = PlotCollection(pf, center=position) p = pc.add_projection("Density", 2) p.set_width(2, 'kpc') for c in range(len(t1clouds)): r = abs(t1clouds[c]['position']-position) if r[0] < 1.0 and r[1] < 1.0: p.modify["point"](t1clouds[c]['position'], str(t1clouds[c]['track'])) p.modify["marker"](t1clouds[c]['position'], marker='o')
pc.save("%s_tracking" % (fn))
But python complains with:
TypeError: text() argument after ** must be a mapping, not NoneType
Did I call the modifier incorrectly?
