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') -Matt On Sun, Jul 8, 2012 at 12:04 PM, Elizabeth Tasker <tasker@astro1.sci.hokudai.ac.jp> wrote:
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?
