2.21 vectors

The 2D vectors style draws a vector from (x,y) to (x+xdelta,y+ydelta). The 3D vectors style is similar, but requires six columns of basic data. A small arrowhead is drawn at the end of each vector.

     4 columns:  x  y  xdelta  ydelta
     6 columns:  x  y  z  xdelta  ydelta  zdelta

splot with vectors is supported only for ‘set mapping cartesian‘. The keywords "with vectors" may be followed by arrow style specifications. See ‘arrowstyle‘ for more details.

Example:

      plot 'file.dat' using 1:2:3:4 with vectors head filled lt 2
      splot 'file.dat' using 1:2:3:(1):(1):(1) with vectors filled head lw 2

‘set clip one‘ and ‘set clip two‘ affect vectors drawn in 2D. Please see clip and ‘arrowstyle‘.
