7 arrange it and find medians needed for box-and-whiskers plotting.

10 Introduction here
11 To show the share deviation of two companies we start by creating two QBoxPlotSeries to handle monthly data.

15 QFile class is used to open a text file where the non-continuous data is kept. The BoxDataReader is an auxiliary class for
16 reading the text file and finding the extreme and median values from the data. The BoxDataReader is explained in more detail later.
17 The method readBox reads the values and sets them to the QBoxSet item which the method returns for the caller. The returned QBoxSet
18 item is added to the series.

22 In this section a second file is opened for reading the data for the second company.

26 In this code snippet a new QChart instance is created and previously created series are added to it. Also title is defined and
27 animation is set to be SeriesAnimation.

31 Here we ask chart to create default axes for our presentation. We also set range for vertical axis by querying the pointer
32 for the axis from the chart and then setting the min and max for that axis.

30 Tarkista numerointi. Finally we add the chart onto a view. We also turn on the antialiasing for the chartView.

32 \snippet ../examples/barchart/main.cpp 6
36 In this section we set legends visible and place them at the bottom of the chart.
33
37
34 Tarkista numerointi. Chart is ready to be shown. We set the chart to be central widget of the window.
38 \snippet ../examples/boxplotchart/main.cpp 6
35 We also set the size for the chart window and show it.

49 Here the method readBox is explained in detail. Firstly a line is read from the file and lines starting with # are rejected
50 since they are considered as comment lines.
51
52 \snippet ../examples/boxplotchart/boxdatareader.cpp 1
53
54 On the file the data is arranged as number, space, number, space and so on. On this snippet the line is split into single number strings which
55 are stored on QStringList.
56
57 \snippet ../examples/boxplotchart/boxdatareader.cpp 2
58
59 The sortedList will hold the numbers in continuous order and in this code segment we show how to do it. First the sortedList is cleared and numbers
60 are read from the strList and stored into sortedList in double format. The qSort method arranges the sortedList into continuous order
61 starting from the smallest.
62
63 \snippet ../examples/boxplotchart/boxdatareader.cpp 3
64
65 Here is a code sample how to select extremes and medians from the continuous data. Firstly a new QBoxSet is created.
66 Lower and upper extremes are simple to select; they are just first and last items on the sortedList. For medians we use a helper
67 method findMedian which is explained later. For the median from the upper half we need to adjust the begin number if
68 amount of the numbers is even or uneven. The end number for lower half comes naturally from int rounding.
69
70 \snippet ../examples/boxplotchart/boxdatareader.cpp 4
71
72 Here's the code sample for the method findMedian. If the amount of numbers is uneven we select the number from
73 the middle. For even amount numbers we take two numbers from the middle and calculate the mean value.
