HELP About contour command

My question is this, i have X and Y points, and for each coordinate there are a Z value, this is not a function, for example:

X=2 , Y=3 and Z=6.7

There are a different vectors for each coordintes, So is a anyway to represent this grafically like contour? o in the way increase de Z value change the color of the graphic?

PS: Sorry my poor english

You could use scatter3 to show a scatter plot of the data:

doc scatter3

Or you could interpolate your data to a regular grid using TriScatteredInterp and then use contour

doc TriScatteredInterp

i used scatter3 and works, but my problem is the points are all with the same color, and i need diferent color while increase the Z value

[Walter Roberson]

pointsize = 8;
scatter3(X(:), Y(:), Z(:), pointsize, Z(:))
