Dear Ben Root,
Thanks for letting me know. I tried again, and finally made a pull 
request. Please let me know if it works this time. Thanks.
If there is something I can do to improve the code, please just let me 
know, and I will be happy to do it.
Regards,
Jianfeng

Take a look at the extent argument to imshow. 
http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot.imshow
You want something like extent=[0,1,0,1]

Hello,
i am actually trying to plot a vector field over a scalar field, 
i want to show a vector field on the intervall x=[0,1] y=[0,1]
this works fine so far, actually i have the problem that if i plot the
scalarfield
via imshow() the image geht scaled by the size of the array.
i.e. if i have a 100x100 array the image is drawn on an [0,100] intervall,
is there any possibility to bring the image down to an [0,1 ] intevall
independent of the array size ? 
thanks
