GNUPlot Manual

134 gnuplot 4.0 36 SET-SHOW
plot coordinates can be obtained calling "gnuplot axisranges". If the "interactive" option is specified,
mouse clicking on a line segment will print the coordinates of its midpoint to stdout. Advanced actions
can happen instead if the user supplies a procedure named "user gnuplot coordinates", which takes the
following arguments: "win id x1s y1s x2s y2s x1e y1e x2e y2e x1m y1m x2m y2m", the name of the
canvas and the id of the line segment followed by the coordinates of its start and end point in the two
possible axis ranges; the coordinates of the midpoint are only filled for logarithmic axes.
The current version of tkcanvas supports neither multiplot nor replot.
36.59.70 Tpic
The tpic terminal driver supports the LaTeX picture environment with tpic \specials. It is an alternative
to the latex and eepic terminal drivers. Options are the point size, line width, and dot-dash interval.
Syntax:
set terminal tpic
where pointsize and linewidth are integers in milli-inches and interval is a float in inches. If a
non-positive value is specified, the default is chosen: pointsize = 40, linewidth = 6, interval = 0.1.
All drivers for LaTeX offer a special way of controlling text positioning: If any text string begins with
’{’, you also need to include a ’}’ at the end of the text, and the whole text will be centered both
horizontally and vertically by LaTeX. — If the text string begins with ’[’, you need to continue it with:
a position specification (up to two out of t,b,l,r), ’]{’, the text itself, and finally, ’}’. The text itself may
be anything LaTeX can typeset as an LR-box. \rule{}{}’s may help for best positioning.
Examples: About label positioning: Use gnuplot defaults (mostly sensible, but sometimes not really
best):
set title ’\LaTeX\ -- $ \gamma $’
Force centering both horizontally and vertically:
set label ’{\LaTeX\ -- $ \gamma $}’ at 0,0
Specify own positioning (top here):
set xlabel ’[t]{\LaTeX\ -- $ \gamma $}’
The other label – account for long ticlabels:
set ylabel ’[r]{\LaTeX\ -- $ \gamma $\rule{7mm}{0pt}}’
36.59.71 Unixpc
The unixpc terminal driver supports AT&T 3b1 and AT&T 7300 Unix PC. It has no options.
36.59.72 Unixplot
The unixplot terminal driver generates output in the Unix "plot" graphics language. It has no options.
This terminal cannot be compiled if the GNU version of plot is to be used; in that case, use the gnugraph
terminal instead.
36.59.73 Atari ST (via VDI)
The vdi terminal is the same as the atari terminal, except that it sends output to the screen via the
VDI and not into AES-Windows.
The vdi terminal has options to set the character size and the screen colors.
Syntax:
set terminal vdi {} { ... }
