[gmx-users] Population Density Plot

[João Henriques]

How does that reply the OP's question? To calculate the joint probability
distribution you need to perform a kernel density estimation. I'd recommend
either SciPy or Seaborn if you're not averse to coding in Python:

https://seaborn.pydata.org/examples/joint_kde.html

With Seaborn this is an incredibly simple task.
