4 columns: x y xdelta ydelta 6 columns: x y z xdelta ydelta zdelta
In both cases, an additional input column (5th in 2D, 7th in 3D) may be used
to provide variable (per-datapoint) color information.
(see linecolor (p. ) and rgbcolor variable (p.
)).
splot with vectors is supported only for set mapping cartesian.
The keywords "with vectors" may be followed by an inline arrow style specifications, a reference to a predefined arrow style, or a request to read the index of the desired arrow style for each vector from a separate column. Note: If you choose "arrowstyle variable" it will fill in all arrow properties at the time the corresponding vector is drawn; you cannot mix this keyword with other line or arrow style qualifiers in the plot command.
plot ... with vectors filled heads plot ... with vectors arrowstyle 3 plot ... using 1:2:3:4:5 with vectors arrowstyle variable
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.

).
