Gnuplot
is a command-driven interactive plotting program. It is
is included in many Unix distributions like Gnu/Linux. While often
used it as a graphics calculator, its features go way beyond that.
|
|
To start, type "gnuplot" from a terminal and type at the
prompt "gnuplot>" the command "plot sin(x)".
An other good way to start is "help example".
|
|
Example 1:
|
An external
C program randdata.c
produces a data file, which is plotted by
the gnuplot program example1.gp .
|
|
Example 2:
|
The example example2.gp shows
how to plot a surface additionally bounded by other surfaces.
|
|
Example 3:
|
The example example3.gp shows
how to plot level curves and how to redirect the output as a
ps file.
|
|
Example 4:
|
The example example4.gp shows
how to draw a graph as a LaTeX
picture.
|
|
More examples can be found on
gnuplot-faq
site.
|
|
You can grab these examples together with a
Makefile at once as a
gziped tar ball gnuplot.tgz .
Unwrap it with "gunzip gnuplot.tgz; tar -xf gnuplot.tar", go
to the directory "gnuplot", type "make example1" until
"make example4" and finish with "make clean".
