r983 The example shows how to create chart which presents the same set of data as line, scatter, spline and area charts.
ChartPresenter will switch between these four chart types every few seconds. Note: You can also use the
QAbstractItemModel related APIs to pass data for the different series types. See the \l {Model data example} for
more details.

Class will implement \c handleTimeout() slot which we are going to use to trigger switching between different chart presentations.

r574 We are also going to provide \c handlePoitClicked() slot which will show clicked point on the chart.

r482 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

r574 using QLineSeries , as scatter chart using QScatterSeries, as a spline chart using QSplineSeries and a area chart using QAreaSeries. We create needed instances in constructor of ChartView class.

r574 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.

In \c handlePointClciked() slot we set the chart's title to show clicked point x and y coordinates.
