Contour(X,Y,Z), grid contour with regard to probability or distance costs

Hi! Can contour work to create grid contour? My data is like this. I want to create graph like

 (1) x y are column 1 and column 2 as the grid coordinate
 (2) column 3 is the costs "Z". In applications, column 3 is the distance.

I can do this according to the matrix of second picture. But the generated graph only shows an average contour. I wanna try to generate one like the third graph. Did i try the right function or there is other more suitable one than contour()? Thank you!

if true
  %code
D0o(3,4) = sum(A34_0o(:,3))/100;
D0o(3,5) = sum(A35_0o(:,3))/100;
D0o(3,6) = sum(A36_0o(:,3))/100;
...
pcolor(D0o);

end

I now creat a 12x12 martix D0o, and the elements indicates the average distance between M and N. So I use pcolor(D0o) to drwa the graph. But it is not intended actually. Because it cannot display the detailed distance costs or probability as what i want(like the graph link). I was thinking about whether there are functions like

if true
  % code
contourf(A(:,1),A(:,2),A(:,3));
pcolor(A(:,1),A(:,2),A(:,3));
end

Perhaps the contourf function is what you're looking for. Another possibility would be pcolor .

Yes, I've already tried that but it seems they cannot work as expected. Only when i sum and average the data to be a MxN matrix it works well, but the graph cannot show the cost of each coordinate. I add a piece of code in the description. Hope it can be helpful.

I see. I wasn't sure whether you were after the gridding part or the display part.
