max values and y-val of 0

include max data values (previously were left out of plot)
include max y values (previously were left off of y axis)
show y scale such that height of column in histogram corresponds to
  correct y value (previously corresponded to y-1)
no need to include 0 in ys. Rather, start ys at min of 1, and
  leave cols with y val of 0 empty.
