Hi everybody,
I have a matrix A=[x,y,temperature] with a lot of rows in each column. I would like to have a continuous colormap (preferably with the equipotential) of the temperature assign to each points. I am able to have the scatter with color, but it's difficult to see the evolution in space (see picture below). I have tried with surf, with contourf, but nothing seems to work (at least when I try with the other example I saw).

Hi,
I don't have much to show in terms of attempt, because nothing would give me something close to what I expected. I putted the variable I use in attachment file.
figure(1)
contourf(A)
surf(A)

load('A.mat')
x = A(:,1) ;
y = A(:,2) ;
z = A(:,3) ;
nx = length(unique(x)) ;
ny = length(unique(y)) ;
X = reshape(x,nx,ny) ;
Y = reshape(y,nx,ny) ;
Z = reshape(z,nx,ny) ;
pcolor(X,Y,Z) ;
