Re: [Gnuplot-info] How to place values on a columnstacked histogram?

[Ethan M. <eam...@gm...>]

This could maybe serve as a starting point.  The placement is not pretty
but it shows the basic principle.

plot $Data u 2 ti col , '' u 3:key(1) ti col, \
     ysum=0 '' skip 1 using (0):((ysum = ysum + $2, ysum-5)):2 with labels
notitle, \
     ysum=0 '' skip 1 using (1):((ysum = ysum + $3, ysum-5)):3 with labels
notitle
