- \class QBoxSet
- \inmodule Qt Charts
- \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.
