[Matplotlib-users] Bbox::update_numerix_xy expected numerix array

[Alen R. <ale...@gm...>]

I get the following error when its gets to the line where the bar(...)
function is called:

"Bbox::update_numerix_xy expected numerix array"

What does this mean? is it referring to the the left, height or width...?

If I execute the same code form the command line it works! But, If I
call the code from a Web Application then is gives me that error
above.

I tried via the pylab and matplotlib api. Both give the same error.

Thx
