#1985: histogram2d

 I notice that when I plot two variables, the x and y axis are flipped
 according to the online example, so I did a simple distribution of points

 x=np.array([ 1,  2,  3,  4,  5,  6,  7,  8,  9, 10,  1])
 y=np.array([ 10,  20,  30,  40,  50,  60,  70,  80,  90, 100, 100])
 H, yedges, xedges = np.histogram2d(y,x)
 extent = [xedges[0], xedges[-1], yedges[0], yedges[-1]]
 pylab.imshow(H, extent=extent,
 interpolation='nearest',origin='lower',aspect='auto')

 I had to enter into histgram2d() the "y" before the "x" to get the graph
 to come out as expected.
