bars height on hist3 depends on frequency of first and second variable. How can I height of those bars be related to another variable. Maybe hist3 is not the right function to achieve that.
Thanks

What about bar or bar3? For bar3, the height of the bar is whatever you specify, e.g.
x = 1:5;
y = 1:10;
[X, Y] = meshgrid(x, y);
Z = sqrt(X.^2 + Y.^2);
figure;
bar3(y, Z);
axis tight;
Does this do what you want? If not, please explain in the comments.

I have 3 vectors, same lenght (1000 x 1), I want to plot first and second variable as X and Y in the graph, group first and second variable in range to get only 5 x 4 or something else ranges.Z is the third variable and gets the height of every bar that is in the range. Hope I explain a little bit more.
