Hi Nathan, Thank you very much for your reply! There is no error message after this modification, but there is still no title on the pdf/png I get. It's strange. Pengfei 2012/7/16 Nathan Goldbaum :

Hi Pengfei,

I think you want to replace this line:

p.modify["title"](halos, text='z=%.2f'%z)

With the following:

p.modify["title"]('z=%.2f'%z)

Cheers,

Nathan

Hi,

I'm trying to add a title for the picture, but I can't find the right command to do so. Here is the code:

pf = load(fn) halos = HaloFinder(pf) pc = PlotCollection(pf, [pos_x, pos_y, pos_z]) p = pc.add_slice("Density", 0) pc.set_width(3*rad, '1') p.modify["hop_particles"](halos, max_number=100, alpha=0.3) p.modify["title"](halos, text='z=%.2f'%z)

And there is some error reported for the last line. The meaning of the error is more than one name is given to the title. Then I replace it with:

p.modify["text"](halos, pos=(0.02, 0.98), text='z=%.2f'%z)

But it still has error. Could someone please help me about it?

Hi Sam, Thank you so much! Now it works:-) Have a nice day! Pengfei 在 2012-7-17，8:12，Sam Skillman 写道：

Hi Penfei,

It seems there might be a bug in the title callback. In the meantime while we fix the bug (I will file an issue to be resolved), you may want to use the text callback:

If you want some text over on the right side near the colorbar, you should have decent luck with:

p.modify['text']((1.15,0.9), 'z=%.2f'%z)

or if you want to place it in the middle, which you'd probably want the color to be white, you could do something like:

p.modify['text']((0.5,0.9), 'z=%.2f'%0.1, text_args={'color':'w'})

The numbers in the () denote the fractional position in x,y in the image part of the plot. In both of those examples, I'm assuming you've defined z somewhere, otherwise is will still fail.

Best, Sam
