this is my new topic here.
I have three variables (x,y,z) and another variable f(x,y,z). x,y, and z take the values from 0 to 19, and for each value of (x,y,z) I have a value for f(x,y,z). which means 20 values for x, y, and z. But f has 20x20x20=8000 values.
I want to represent the data like the following figure using python.
