[Matplotlib-users] text with gridspec

[Claus H. <cla...@gm...>]

Hi,
I am trying to produce a set of plots using grispec. There should be an images shown in each of the axes (using imshow) except in one of the axes, where I want to show/plot some text. However, the text seems to be too long to be displayed in one line. Is there a way to print it in something like a text box? 

I created a minimal example (see below). 'circle.png' can be seen as a placeholder for some png file.
There are two examples I found on stackoverflow. But I am not sure how they could be applicable here
    http://stackoverflow.com/questions/5777576/is-there-a-way-of-drawing-a-caption-box-in-matplotlib
    http://stackoverflow.com/questions/4018860/text-box-in-matplotlib

I can not / do not want to make a string variable with three quotation marks (docstring), because I am reading the text from a bigger ascii file.

Also, I am not sure if gridspec is the best way to do this.
Thanks for pointers!
