This is the most natural approach.
Also, you can draw pairs of points, the extrems of the segments, with
option 'points_joined' equal to 'true'. This gives more flexibility; for
example, if you want non vertical segments, or if they don't need to
reach the x-axis.
Also, you don't need to set option 'color' to 'blue', since this is the
default value.
