\brief Building block for box-and-whiskers chart
|
|
|
|
|
|
QBoxSet represents one box-and-whiskers item. It takes fives values to create a graphical representation
|
|
|
of range and three medians. There's two type of methods to give the values. The first one is with constructor
|
|
|
or append type of methods (append and operator <<). In these the values have to be given in order lower extreme,
|
|
|
lower quartile, median, upper quartile and upper extre. Second method is to create an empty QBoxSet instance and
|
|
|
give the values using own methods.
