Hello

I'm from Spain, sorry for my english.I saw your question about gnuplot in a forum and i think you could help me.

2,3,4,4,2,4,3,4,2,4

The solution is: 

2--->30%
3--->20%
4--->50%

how can i do this?Thanks

You'll have to change that file into a format gnuplot can use: each 
number on a line of text of its own.

Only with help from outside gnuplot.  gnuplot isn't meant to be a data 
processing program.  In the case at hand, you need external tools to 
count the number of entries in the file.  In the simplest imaginageable 
case, this would do it:

	count=`wc -l data`  # use external tool 'wc' to count items
	set boxwidth 1
	plot 'data' using 1:(100.0/count) smooth frequency with boxes
