12.3.2.1.3 Reproduce the Waterfall Plot Using SGPLOT

A NEEDLE plot statement in SGPLOT can be used to easily produce the bars

in a waterfall plot. A needle becomes a bar when the thickness of the line is

increased (thickness = 6 is used in the example).

Needle plots use vertical line segments to connect each data point to a
