Contour Plot from Coordinates

Right now I have a matrix with x-coordinates, matrix with y-coordinates, and a matrix with pressure values at these points. I'm trying to create a pressure contour plot based on the pressure values at these points, but I cannot seem to figure it out. Could anyone point me in the right direction of how to accomplish this? Any help would be much appreciated!

I will assume you have three vectors: x, y, and z (where z represents pressure). For example
x = rand(1,100);
y = rand(1,100);
z = x.^2 + y.^2;
Then, you can try
[xi, yi] = meshgrid(...
linspace(min(x),max(x)),...
linspace(min(y),max(y)));
zi = griddata(x,y,z, xi,yi);
contour(xi,yi,zi)

surely, this worked great. But the contour that I got looks like a quarter of a circle. Can you please tell me how to get a contour like a full circle. Thanks!
