Google Charts is harder at first but would be a good investment as it is
the basis of the jgc verb (J Google Charts) used in the jhs version of
J701. jgcx'' gives several examples of what is possible including
putting several graphs in the same display. You probably need the
xlinexy feature as in
'reset xlinexy &chs=360x270 show' jgc 1 2 3 2 ; 0 1 0 0.5
to show a path from 1 0 to 2 1 to 3 0 to 2 0.5 .
It is easy to get multiple paths each with its own color and label, see
examples provided by jgcx'' . (For multiple paths append additional x
and y coordinate boxes.)
