 r2712 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.

 r2727 \brief Series for creating box-and-whiskers chart.
Titta Heikkala
Qt Charts project file structure change...
 r2712 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:
\code
import QtQuick 2.0
import QtCharts 2.0
ChartView {
title: "Box Plot series"
width: 400
height: 300
theme: ChartView.ChartThemeBrownSand
legend.alignment: Qt.AlignBottom
BoxPlotSeries {
id: plotSeries
name: "Income"
BoxSet { label: "Jan"; values: [3, 4, 5.1, 6.2, 8.5] }
BoxSet { label: "Feb"; values: [5, 6, 7.5, 8.6, 11.8] }
BoxSet { label: "Mar"; values: [3.2, 5, 5.7, 8, 9.2] }
BoxSet { label: "Apr"; values: [3.8, 5, 6.4, 7, 8] }
BoxSet { label: "May"; values: [4, 5, 5.2, 6, 7] }
}
}
