\brief Building block for box-and-whiskers chart.
|
|
|
|
|
|
QBoxSet represents one box-and-whiskers item. It takes five values to create a graphical representation
|
|
|
of range and three medians. There are two ways to give the values. The first one is with constructor
|
|
|
or stream operator (<<). The values have to be given in the following order: lower extreme,
|
|
|
lower quartile, median, upper quartile and upper extreme. The Second method is to create an empty QBoxSet instance and
|
|
|
give the values using setValue method.
