\brief A plot item, which displays a zone
|
||
|
|
|
||
|
|
A horizontal zone highlights an interval of the y axis - a vertical
|
||
|
|
zone an interval of the x axis - and is unbounded in the opposite direction.
|
||
|
|
It is filled with a brush and its border lines are optionally displayed with a pen.

\note For displaying an area that is bounded for x and y coordinates
