## 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 <pointsize> <linewidth> <interval>

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}}'
