plotting non-numeric and non-time data on x axis
Negandhi, Hiten
Is there any way in GNUPlot of plotting a non-numeric or non-time data on
the X/Y axis?
For my database, I want to plot "file name" on x axis, and number of
read/write requests for that file on the Y axis. Is there any way to use
GNUPlot to do this?
Any help will be highly appreciated, thanks!

Is this what you want?

File1 20
File2 10
File3 50
File4 50
File5 90
So, I want to build my xtics dynamically using the first parameter from the
datafile. I wish I could say something like this
set xtics $1

set xtics ("File1" 1,"File2" 2,"File3" 3,"File4" 4,"File5" 5)
set xr [1:5]
plot 'data' u ($0+1):2 notitle w l
pause -1
This will give you what you want. You can generate this script
automatically.

To supress the x-axis labels:
unset xtics
To plot a one column data file using an implied
x-axis:
plot "file.ext" 0:1 with points
Does that help?

This should be:
plot 'file.ext' u 0:2 w p
but your method has no xtics at all which is not what he needs.

See my attached response to an earlier question (Subject "Gnuplot" posted on
6/14 by Markus Latzel) for how to use awk to generate the tic labels
automatically (in that case for the Y axis).

This'll do it:
set ytics (`awk '{printf("%s%s%s%s %d",sep,ti,$1,ti,NR-1);sep=", "}' ti="'"
datafile.dat`)
plot 'datafile.dat' using 2:0:(0.0):2 with xerrorbars pt 0
but your order of Names will be inverted since Name1 is the first (zero-th)
row.
If you want them un-inverted this would reverse the order of names in the
awk
script:
set ytics (`awk '{name[NR]=$1}END{for (i = NR; i > 0; i--)
{printf("%s%s%s%s%d",sep,ti,name[i],ti,NR-i);sep=", "}}' ti="'" tst1.dat`)
and presumably you could do something similair (or better!) with the plot
line,
or just reverse input file e.g. using "tac" on UNIX.

But, instead of "File1" thru "File5", it can have any text like "ABC1" thru
"ABC5" also.
How can I dynamically generate the set tics command to read the data file?

Suppose you data file name is 'data'
set xtics ("File1" 1,"File2" 2,"File3" 3,"File4" 4,"File5" 5)
set xr [1:5]
plot 'data' u ($0+1):2 notitle w l
pause -1

See one of the other responses in this thread for a script example.

CVS version of gnuplot + patch #595850 from gnuplot SourceForge site.
More information and latest version of patch available at
http://www.bmsc.washington.edu/people/merritt/gnuplot
With this patched version you can generate your plot using the command
plot 'data' using 2:xtic(1) with impulses
That means "take data values from column 2 and corresponding xtic
labels from column 1".

You can write a scipt that can dynamically change the tics according to
your data files. There should be no problems with this.
