## Spiderplot

The set spiderplot command switches interpretation of coordinates to a polar system in which each data point is mapped to a position along a radial axis. paxis 1 is always vertical; axes 2 to N proceed clockwise with even spacing. The command must be issued prior to plotting. It has additional effects equivalent to

        set style data spiderplot
        unset border
        unset tics
        set key noautotitle
        set size ratio 1.0

Use reset to restore these after plotting.
