This position is specified by the syntax: {<system>} <x>, {<system>} <y> {,{<system>} <z>} Each <system> can either be `first`, `second`, `graph` or `screen`. `first` places the x, y, or z coordinate in the system defined by the left and bottom axes; `second` places it in the system defined by the second axes (top and right); `graph` specifies the area within the axes---0,0 is bottom left and 1,1 is top right (for splot, 0,0,0 is bottom left of plotting area; use negative z to get to the base---see `set ticslevel` (Note: ticslevel )); and screen specifies the screen area (the entire area---not just the portion selected by `set size` (Note: size )), with 0,0 at bottom left and 1,1 at top right. If the coordinate system for x is not specified, `first` is used. If the system for y is not specified, the one used for x is adopted. If one (or more) axis is timeseries, the appropriate coordinate should be given as a quoted time string according to the `timefmt` (Note: timefmt ) format string. See `set xdata` (Note: xdata ) and set timefmt. . `gnuplot` (Note: gnuplot ) will also accept an integer expression, which will be interpreted as seconds from 1 January 2000. automatically generated by info2www version 1.2.2.9 |
