newspiderplot

Normally the sequential elements of a plot command with spiderplot each correspond to one vertex of a single polygon. In order to describe multiple polygons in the same plot command, they must be separated by newspiderplot. Example:

     # One polygon with 10 vertices
     plot for [i=1:5] 'A' using i, for [j=1:5] 'B' using j
     # Two polygons with 5 vertices
     plot for [i=1:5] 'A' using i, newspiderplot, for [j=1:5] 'B' using j
