Matlab：如何在（x，y，z）坐标中绘制堆叠的3D条形图？

Question

I'd like to plot a stacked 3D bar in three-dimensional coordinates, ie, given x, and y, z is a stacked 3D bar. It seems like Matlab only supports such plot in two-dimensional coordinates.

for example, how to plot such a stacked 3D bar in (x,y,z) space using the following data sets?

    x, y, z
    1, 2, (3+4)
    1, 1, (5+6)
    2, 1, (1+1)

Thanks!

Answer 1

You have two general approaches you can take...

1. Plot your own bars (ie cuboids): You can create a function that takes the sets of values and plots the cuboid surfaces at those points. There are a few ways to create basic 3D cubes, which are covered in this question and this MATLAB Newsgroup thread . You would just have to scale, shift, and recolor the cube surfaces accordingly. If this seems a daunting task, then...

2. Make multiple BAR3 plots, modifying each accordingly: This question covers how to make a grid of stacked bar plots. In your case, you probably wouldn't want a full grid, but sparse stacked bars scattered at different coordinates in a region. In this case, you could format your data to work with the solution in the above question by creating 2-D sets of data for z , filled with zeroes where you don't want any bars. Then you can remove the unwanted zero-value bars at each step using the solutions from this question .
