I use matplotlib since two days only. I have done some things pretty

good but I am now in front of a problem an I didn't found a solution

in the documentation.

I would like to draw the surface defined by the lists X, Y and the matrix Z.

I get to a nice graphical output with the following code.

My problem is that the labels on the axes indicate values

corresponding to the indices in Tables X and Y or something like that.

I would like to see the values between xmin and xmax, ymin and ymax.

If I uncomment the lines set_xlim and set_ylim, the axes are properly

represented, but the picture is shrinked into a corner.

How to put the good values on the axes and correct the image full

screen and correct scale ?

Thank you in advance.

#! /usr/bin/env python

from pylab import *

x=[0,1,2,3]

y=[12, 32,81]

z=[2,3,1,4,2,5,6,8,10,4,11,3]

Z=zeros((len(x),len(y)))

count=0

for i in range(0,len(x)):

for j in range(0,len(y)):

Z[i,j]=z[count]

count=count+1

ax = subplot(111)

im = imshow(Z, interpolation='bilinear')

xmin=x[0]

xmax=x[len(x)-1]

ymin=y[0]

ymax=y[len(y)-1]

#ax.set_xlim(xmin,xmax)

#ax.set_ylim(ymin,ymax)

#axes().set_aspect('auto',adjustable='box')

colorbar()

show()
