Hi Luigi,

Dear all,
I would like to overplot a line to a slice of mine. I use the line callback, for example with the following sintax:
p.modify["line"]((0,639),(30,30))
if I have well understood, the two pairs of numbers are pixel-based coordinates. I have a few questions:
1) where is the range of these number set (i.e., the image size in pixel), and how can I eventually modify it?
It's usually set in the figure creation.
2) Is it any simple way to define the begin and end points of a line in other coordinates? Code coordinates from 0 to 1 would be enough;
Yup, use the 'image_line' callback instead. (We really need a better documentation system for the callbacks!)
3) How do I modify the features of the line (e.g. thickness, color)?
You can supply a dict as the keyword plot_args, which will get passed to matplotlib's 'plot' command. So any arguments can be supplied to that. i.e., p.modify["image_line"]((0.1,0.3), (0.4,0.5), plot_args={'c':'b', 'lw':2.5}) This sets color to blue, linewidth to 2.5. -Matt
Thanks in advance,
Luigi
