Gnuplot: Plotting 3D Points with splot Command

[physguy2]

Hello all,

I am having an issue with the splot command in gnuplot.

The format of the data I am trying to plot is shown below:

3.09411   71.75663   -2.17624
3.09238   67.64099   -1.94456
3.10106   73.70542   -2.85122
3.09494   75.71568   -3.49932
3.09846   75.29150   -1.14593

My current attempts have led me to numerous websites on gnuplot tutorials, but none have done the job.

I am looking to plot these points with the second column as x, the third as y, and the first column as z.

This is what I have so far (which gives me an empty plot):

set zrange [3.08:3.11]        
set yrange [-8:8]      
set xrange [65:90]  
splot "xphase.txt" using 2:3:1

Thank you in advance for your help!

Take a look at http://t16web.lanl.gov/Kawano/gnuplot/plot3d2-e.html

and http://riotorto.users.sourceforge.net/gnuplot/points/index.html

"Maxima" site at http://maxima.sourceforge.net/

Maybe you want to use "maxima" as a front end to gnuplot.
