Plot
</H1>
<B>plot</B> is the primary command for drawing plots with <B>gnuplot</B>. It creates
plots of functions and data in many, many ways. <B>plot</B> is used to draw 2-d
functions and data; <B>splot</B> draws 2D projections of 3D surfaces and data.
<B>plot</B> and <B>splot</B> contain many common features; see <B>splot (p. <A HREF="node335.html#splot"><IMG ALIGN="BOTTOM" BORDER="1" ALT="[*]" SRC="crossref.png"></A>)<A NAME="2558"></A></B> for differences.
Note specifically that although the <B>binary 4#4binary list5#5</B> variation does
work for both <B>plot</B> and <B>splot</B>, there are small differences between these
modes.
<P>
Syntax:
<BR>
<PRE>
plot {<ranges>}
{<iteration>}
{<function> | {"<datafile>" {datafile-modifiers}}}
{axes <axes>} {<title-spec>} {with <style>}
{, {definitions{,}} <function> ...}
</PRE>
<BR>
<P>
where either a 4#4function5#5 or the name of a data file enclosed in quotes is
supplied. A function is a mathematical expression or a pair of mathematical
expressions in parametric mode. The expressions may be defined completely or
in part earlier in the stream of <B>gnuplot</B> commands (see <B>user-defined (p. <A HREF="node31.html#user-defined"><IMG ALIGN="BOTTOM" BORDER="1" ALT="[*]" SRC="crossref.png"></A>)<A NAME="2566"></A></B>).
<P>
It is also possible to define functions and parameters on the <B>plot</B> command
itself. This is done merely by isolating them from other items with commas.
<P>
Examples:
<BR>
<PRE>
plot sin(x)
plot sin(x), cos(x)
plot f(x) = sin(x*a), a = .2, f(x), a = .4, f(x)
plot "datafile.1" with lines, "datafile.2" with points
plot [t=1:10] [-pi:pi*2] tan(t), \
"data.1" using (tan($2)):($3/$4) smooth csplines \
axes x1y2 notitle with lines 5
plot for [datafile in "spinach.dat broccoli.dat"] datafile
</PRE>
