[Gnuplot-info] stdin datafile as a variable

[Richard H. <r.h...@rl...>]

Hi Folks,

I would like to do something like the following contrived example:

gnuplot> dataFile = sprintf("\'< ps aux | tail -%d\'", 20)
gnuplot> plot dataFile u 2
         warning: Skipping unreadable file "'< ps aux | tail -20'"
         No data in plot

as the error copied above indicates, I'm not having much joy!

Any suggestions?

r,
