in reply to Multiple Y axes with different scales

What library do you use to plot the graph? There's no plot function in the CORE:: namespace of Perl.

Note that your question is hard to read as you didn't use the recommended markup:

@Somedata = ([1,2,3,4,5], [2,3,4,5,6], [3,4,5,6,7]);

What graph do you expect?

($q=q:Sq=~/;[c](.)(.)/;chr(-||-|5+lengthSq)`"S|oS2"`map{chr |+ord }map{substrSq`S_+|`|}3E|-|`7**2-3:)=~y+S|`+$1,++print+eval$q,q,a,
