I am displaying densities which are written as gOpenMol plt format; I
reckon it's essentially the same for (other) spatial distribution

I attached bits of code that I use to write the files. I am using Gromacs
and have written some code to generate densities from molecular dynamics
trajectories. In principle the code would be available, I just haven't
found the time to make it available through the contributions page of However, the plt output is simple and from plt.{h,c} you
should get an idea what to do. Use it as a guideline; in the form that the
files are now they won't compile because they need other stuff, too. I
should also acknowledge Christoph Freudenberger, who helped me with the
plt output and suggested using it on gmx-users.
