How to make a 3D figure of a furnace which has temperature displayed on its surface?

I have temperature data from thermocouples which are at different height on the surface of furnace. I know their respective heights. The no. of thermocouples are different at different levels. So the whole data cannot be taken in a single matrix. Even if I take average, how to go about it? I have started by assuming some values of temperature. The figure I get from the contour is a broken cylinder and also I want full scale of temperature and not scaled to 0 to 1.

contourf(A);

print contour.tiff -dtiff -r100

file = imread('contour.tiff');

[Xc, Yc, Zc]=cylinder;
h=surf(Xc, Yc, Zc);

h = findobj('Type','surface'); 

pic = file;

set(h, 'CData', pic,'Facecolor', 'texturemap')
