Friends,
I tried to incorporate an example script for colorbar given in the following
link into my code.
http://matplotlib.sourceforge.net/examples/api/colorbar_only.html
When i run the program, i get the following error. I didnt use set_ylabel
option in my code. I am not getting why this error appears. Kindly help me
by writting why this error comes. I have attached the code with the mail.
Thanks,
Bala
