- Files of this format are interpreted by <a href="../man1/plot.html"><i>plot</i>(1)</a> to draw graphics
- on the screen. A <i>plot</i> file is a UTF stream of instruction lines.
- Arguments are delimited by spaces, tabs, or commas. Numbers may
- be floating point. Punctuation marks (except <tt><font size=+1>:</font></tt>) , spaces, and
- tabs at the beginning of lines are ignored. Comments run from
- <tt><font size=+1>:</font></tt> to newline. Extra letters appended to a valid instruction are
- ignored. Thus <tt><font size=+1>...line</font></tt>, <tt><font size=+1>line</font></tt>, <tt><font size=+1>li</font></tt> all mean the same thing. Arguments
- are interpreted as follows:<br>
- 1.&nbsp;&nbsp;&nbsp;&nbsp;If an instruction requires no arguments, the rest of the line
- is ignored.<br>
- 2.&nbsp;&nbsp;&nbsp;&nbsp;If it requires a string argument, then all the line after the
- first field separator is passed as argument. Quote marks may be
- used to preserve leading blanks. Strings may include newlines
- represented as <tt><font size=+1>\n</font></tt>.<br>
- 3.&nbsp;&nbsp;&nbsp;&nbsp;Between numeric arguments alphabetic characters and punctuation
- marks are ignored. Thus <tt><font size=+1>line from 5 6 to 7 8</font></tt> draws a line from
- (5, 6) to (7, 8).<br>
- 4.&nbsp;&nbsp;&nbsp;&nbsp;Instructions with numeric arguments remain in effect until a
- new instruction is read. Such commands may spill over many lines.
- Thus the following sequence will draw a polygon with vertices
- (4.5, 6.77), (5.8, 5.6), (7.8, 4.55), and (10.0, 3.6).<br>
