Hi Constantin,

Yes. :)  For example, to make a 3D scatter plot with BOX markers using the
first three columns of a data file, you can do:

datafile df("myfile.dat");
df.plot(BOX, 1, 2, 3);

In case it's useful, if F is a P-valued function of three doubles, the
command

df.plot(BOX, i1, i2, i3, F);

creates a 3-D scatter plot by passing columns i1, i2, and i3 to F and
plotting the resulting points.

Best,
Andy
