[Matplotlib-users] trace a rectangle

[Humufr <hu...@ya...>]

             Hi,

I have a problem to draw a rectangle:

The first is that I can't arrive to draw a rectangle with ipython 
-pylab, the script who work when it's launch independantly is not 
working interactively. The rectangle is not draw. Perhaps it's normal 
but I don't think.

The second problem I have is to draw a rectangle at a certain position 
with certain height and width. It's seems (at least when I tried to use 
it) that the position must be done relatively at the window and not from 
the plot. It's not very convenient because if I have a plot draw between 
1 and 100 in x and y, to draw the rectangle I add to use something 
between 0 and 1 so I had to rescale the rectangle.

Thanks,

    Nicolas
