bars at specific (x,y) points

I need to create a 3d bar plot with bars at specific (x,y) points. Where X and Y are the coordinates and the temperature column is the corresponding temperature value at each coordinate.
Can someone help me, please?
Thank you so much !!

Matlab can't do that out of the box... :( bar3() is seriously weak in its abilities.
Might search on File Exchange...

You need to store the temperature values in a 2D matrix considering x, y values as row and column indices. For example,
data = [3 28 26.711
4 28 26.711
5 28 26.532
5 27 26.532
5 26 26.711];
barData = zeros(max(data(:,1)),max(data(:,2)));
for k = 1:length(data(:,1))
barData(data(k,1),data(k,2))=data(k,3);
end
bar3(barData)
But remember, you have 0 in x and y coordinates, that's not possible this way. You need to include an offset for this case.

If ‘D’ are your data, so that ‘D(:,1)=X’, ‘D(:,2)=Y’, ‘D(:,3)=T’, try this:
H3 = accumarray(D(:,[1 2])+1, D(:,3), [], @mean);
X = min(D(:,1)):max(D(:,1));
Y = min(D(:,2)):max(D(:,2));
figure(1)
bar3(H3)
grid on
