\brief Building block for box-and-whiskers chart.
|
|
|
|
|
|
BoxSet 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 with append method. In these 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 value specific methods.

\brief Series for creating box-and-whiskers chart.
|
|
|
|
|
|
BoxPlotSeries represents a series of data shown as box-and-whiskers bars. The purpose of this
|
|
|
class is to act as a container for single box-and-whiskers items. Each item is drawn to own
|
|
|
slot. If chart includes multiple instances of BoxPlotSeries then box-and-whiskers items with the
|
|
|
same index are drawn to same slot.
|
|
|
|
|
|
The following QML shows how to create a simple box-and-whiskers chart:
