word wrap

Community matplotlib-users

I am trying to draw some text inside of a rectangle. The text can
be longer than the rectangle, so I would like to wrap the text. I doubt
MPL has this kind of functionality built in, so I am expecting to write it
myself.

I think I read somewhere that it is not possible to get the length of
text in MPL. Is this true? This would be the basic mechanism
needed to implement this.

I just want to know if this is possible or not, and any pointers if
anyone has some.

Thanks,

Hi,

I guess the extent of the rendered text is not known until the figure
is drawn. The link below would be helpful.

http://matplotlib.sourceforge.net/doc/html/faq/howto_faq.html#how-do-i-automatically-make-room-for-my-tick-labels

So. it is possible to know the text length, but you need to wait until
the drawing time.

I guess the legend class might be helpful, as it adjust its position
at the drawing time according to the text size. But wrapping a text
(in general way) seems not easy to me.

Anyhow, the easiest way I can think of is to rely on LaTeX for wrapping.

  text(0.5, 2.5, r"\parbox[b]{2 in}{really really really really really
really long line}", va="top")

It may be a bit tricky to get the right vertical alignment though.

Regards,
