Thread: [Gnuplot-info] how to plot a long row of data?

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Dear All,

I wonder whether there is a way to do "transpose" on a row of data within
gnuplot so that I can plot it to see its feature.

Thanks,

Sincerely,
Jon

Try searching this page for the word 'transpose'.

http://gnuplot.sourceforge.net/demo/image2.html

Is that what you are after?

Thanks for your input, the most relevant line could be

plot 'demo.edf' binary array=64x32 dx=5 dy=10 scan=yx skip=1024
format="%*float%float" using 1 with image

But this command seems weird to me.

I never met with scan= keyword in plot, it could be that these
keywords are accompanying binary. I don't know whether these options
carry over to text file as well.

Thanks for further help,

Jon

Thanks. Your answer enlightened me to use the right keyword to google,
which returned an answer saying that I need external tools to transpose the
text data first. Then, this boils down to a linux question, how can I
possibly transpose a datafile with indefinite entries per row.

Any easy solution to that? Or maybe I just program a little bit on it.

hi Jon,
the question is how your data are organised. i guess transpose means:

X X X X X -> X
	     X
	     X
	     X
	     X

then you can simply do:  tr " " "\n" <in >out
