6 The example shows how to create chart which presents the same set of data as line, scatter and spline charts.
7 ChartPresenter will switch between these three chart types every few seconds.
8 Please note this example does not use common data model. A use of common data model is documented here.[TODO]

13
14 We create simple ChartView class which derives form QChartView.
15
16 \snippet ../example/presenterchart/chartview.h 1
17
18 Class will implement \c handleTimeout() slot which we are going to use to trigger switching between different chart presentations.
19 Class members \c m_series and \c m_titles are going to store series and related titles. In example we are going to present data as a line chart
20 using QLineSeries , as scatter chart using QScatterSeries, and as a spline chart using QSplineSeries. We create needed instances in constructor of ChartView class.
21 We set custom line and points colors.
22
23 \snippet ../example/presenterchart/chartview.cpp 1
24
25 We add data to all three series. We can use add() member function. If data set is large,it is wiser to use shared data model, as described here.[TODO]
26
27 \snippet ../example/presenterchart/chartview.cpp 2
28
29 In the end we store references all the created series and matching titles.
30
31 \snippet ../example/presenterchart/chartview.cpp 3
32
33 In \c handleTimeout() slot we change currently displayed chart by removing previous series and adding next series from the \c m_series list. We also set proper title.

10 10 QCharts is a part of Qt Commercial addons package. It provides a set of easy to use chart
11 11 components which are available for Qt Commercial customers. It uses Qt Graphics View
12 12 Framework, therefore charts can be easily integrated to modern 2D user interfaces. QCharts can
13 13 be used as QWidgets, QGraphicsWidget or QML elements. Users can easily create impressive
14 14 graphs by selecting one of the charts themes.
