Michal Klocek Adds chartPresenter example to docs	r482
Tero Ahola Updated presenter example screen shots	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.
Michal Klocek Updates presenter example documentation	r574	We are also going to provide \c handlePoitClicked() slot which will show clicked point on the chart.
Michal Klocek Adds chartPresenter example to docs	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
Michal Klocek Updates presenter example documentation	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.
Michal Klocek Adds chartPresenter example to docs	r482	We set custom line and points colors.

Tero Ahola Updated presenter example screen shots	r983	We add data to three series. Please note area chart is going to use QLineSeries as the upper line. We can use add() member function.

Michal Klocek Updates presenter example documentation	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.
