MATLAB: How to plot the number on top of 3D Bar Graphs

MATLAB

I have wrote a code to get a 3D Graph:

A=[0.8 0.9 0.98; 0.6 0.7 0.87; 0.67 0.75 0.7; 0.75 0.68 0.75]
bar3(A, 0.5)
set(gca,'XTickLabel',{'Urban' 'Rural' 'Pe area'})
set(gca,'YTickLabel',{'Sunshine' 'Rain' 'Snow' 'Foggy'})

How would I go about plotting the A-values of each of the bars on top of the bars?

MATLAB: Histogram plotting where the x-axis is in multiples of 0.1

You have two options:

1. You can use the histogram command. When calling histogram you can specify your bins:

binwidth = 0.1;
histogram(X,-0.5:binwidth :0.5)

2. The histogram command will create bars that are touching one another, which doesn't quite match your image. If you want bars that do not touch one another, you will have to bin and plot your data in two steps using histcounts and bar.

binwidth = 0.1;
[N,edges] = histcounts(X,-0.5:binwidth :0.5);
ctrs = (edges(1:end-1)+edges(2:end))/2;
barwidth = 0.5;
bar(ctrs,N,barwidth);

MATLAB: I am defining the nodes . the first set is how i want it but when i run it, it gives me the error of #Subscript indices must either be real positive integers or logicals but if i swap the last two enteries it works fine

It works fine either way. What matters is what you will do with that array AFTERWARDS.

crackplanenodes = [ 4 0 7; 4 0.5 7; 4 1 7; 10 0 7; 10 0.5 7; 10 1 7]
crackplanenodes =
            4            0            7
            4          0.5            7
            4            1            7
           10            0            7
           10          0.5            7
           10            1            7
crackplanenodes = [ 4 0 7; 4 0.5 7; 4 1 7; 10 0 7; 10 7 0.5; 10 7 1]
crackplanenodes =
            4            0            7
            4          0.5            7
            4            1            7
           10            0            7
           10            7          0.5
           10            7            1
