Note the difference caused by flipping the 'D' bit is a change in the
slope, or a mirror image of the original controller.

Likewise, a Negative Bipolar Linear plot would have a negative slopping
bipolar characteristic.  The concave curves take on similar
characteristics.
The figure below contains a summary of the approximate shapes of all
supported controller types. Note that
<A HREF="#8.2.4">Section "8.2.4 Source Types"</A>
contains the mathematical formula for the convex and concave curves.
