The documentation about xgraph should probably be updated
or expanded.
xgraph is a separate application that can be downloaded from
http://www.isi.edu/nsnam/xgraph/
but doesn't come with the Maxima installation.
xgraph is an older plotting program and I'm not sure it's still
being maintained, but it still could be useful. I just
downloaded it and tried it out and it is very easy to install.
# at the bash prompt as a normal user
zcat xgraph-12.1.tar.gz | tar xvf -
cd xgraph-12.1
./configure
make
# switch to root account for install
su
make install
exit
I executed your commands from within Maxima and
got the data plot.
load(bessel)$ sample:makelist([i,gauss(0,1)],i,1,50)$
xgraph_curves([sample]);
|Is it possible to plot data with Maxima+Gnuplot?
As an alternative to openplot, you can invoke
Gnuplot easily to graph 'functions' with:
set_plot_option([plot_format,gnuplot]);
plot2d(x^2,[x,-2,2]);
The only way I know to use Maxima+Gnuplot
to plot data is to save the data as text
file and use Gnuplot (or Octave, R, or even
a spreadsheet) to do the plot.
