MATLAB: How to make 3D bar plot based on their individual coordinates (X,Y)

barbar3chart;coordinatesMATLABscatterbar3

Is there a function that can plot data points (Z) as a 3D bar based on their individual coordinates (X, Y)?

The built-in "bar3" function only plots M-by-N matrix and the bars are evenly distributed.

The following file-exchange submission for "scatterbar3" can be used as a workaround:

MATLAB: How to explicitly change the colors of the bars in a stacked bar graph

You can use the Color Data (CData) property for bar graph released in R2017b.

You can change the color for a particular bar by setting the FaceColor property to 'flat'. Then, change the corresponding row in the CData matrix to the new RGB triplet. Here is the link for the CData property in bar graph:

For example,

a = [1,3,6;2,5,6;8,2,1];
H=bar(a, 'stacked');
colorSet = [];
for i = 1:3
    myColors = round(rand(3,3),1);
    colorSet = [colorSet myColors];
    H(i).FaceColor = 'flat';
    H(i).CData = myColors;
 end
This will display the stacked bar plot with different colors.
