How can I create an x,y plot where the grid spacing is not equal?

I have a 5x50 matrix of temperature measurements taken across a metal plate which I would like to plot. The spacing of the x-axis measurements was 1.1cm and the y-axis was 0.6cm. Somehow I need to plot the measurements according to this spacing and interpolate the temperatures between the measurements. Here's what I have so far:
% Temperature data is stored in T
[X,Y]=meshgrid(0:1.1:4.9,-15:0.6:14.4);
contourf(X,Y,T)
title('Temperature Distribution')
I am not convinced this is producing the correct result also, I am not able to interpolate the shading when using contourf, if there a better plot to use?

What makes you think this is incorrect?
What is the purpose of the visualization?

You might prefer to interpolate the data first, before plotting. Look at the help for interp2, perhaps with method set to bicubic.
