Quantify 3D-scatter property areas

Hello,

there is tricky problem I just cant solve with my basic MATLAB skills.

I have a 3D-scatter plot with colour code (that refers to the term property in the caption).

What I would like to do is segment the 3D-scatter plot coordinate system into smaller cube-like shapes and sum up the property values of the corresponding points inside of these cubes to compare them with each other.

Can you think of a way how to solve this problem? I hope this was understandable.

Best wishes!
