Re: Graphing a list of values

[Alex fxmbsw7 Ratchev]

here my awk try

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