Re: Graphing a list of values

[Alex fxmbsw7 Ratchev]

i posted awk code that does similiar
you can extract $2 by a awk '{ print $2 }' before it, and not using ${t[*]}
for your data piped as input

just curious, did you recieve a mail post with the awk code ?

let me actually fix up the code for your usage

printf %s\ %s\\n @ 20 + 100 . 50 | awk '{ print $2 }' | gawk -v c=15 -v S=+
'{ m = m < $1 ? $1 : m ; s[NR] = $1 } END { while ( ++i <= NR ) print l(
int( s[i] / m * c ) ) } function l( n, t ) { t = sprintf( "%-" n "s", "" )
; gsub( " ", S , t ) ; return t }'
