[Gnuplot-info] Plotting y-data vs two x-axis points?

[Praedor A. <pr...@ya...>]

Thank you for the fast response.

I have another question to build from the previous and one question on gene=
ral=20
usage.  First, now that I can plot each column separately and above the=20
appropriate x-axis label, if I then wanted to connect the two points with a=
=20
line how would I do this?  They are in separate columns...

=46inal question relates to adding error bars to the plots.  I have been ab=
le to=20
get error bars plotted with the points but so far I had to do so in a=20
separate plot overlay, ie:

plot './datafile.csv' using 2:3 with points pointtype 6 pointsize 2, '' usi=
ng=20
2:3:5 with yerr

I have tried what SEEMED natural but it errors out:

plot 'datafile' using 2:3:5 with points pointtype 6 pointsize 2 yerr

When you need to plot data using multiple parameters that use the "with"=20
command, how do you do it when the gnuplot commandline wont accept them all=
=20
in one line/command string?
