\example examples/zoomlinechart
\title Zoom line example
\subtitle
The example shows how to create your own custom zooming effect with QRubberBand by using a mouse
and how to use touch gestures for paning and zooming.

Let's first create a line series with some example data.
\snippet ../examples/zoomlinechart/main.cpp 1
Then we create a custom chart view by deriving from QChartView:
\snippet ../examples/zoomlinechart/chartview.h 1
We override mouse and key event handling
\snippet ../examples/zoomlinechart/chartview.h 2
Then we implement a custom logic for mouse and key events. For example pressing '+' key will zoom in and pressing
the '-' key will zoom out.
\snippet ../examples/zoomlinechart/chartview.cpp 1
We also create our own QChart:
\snippet ../examples/zoomlinechart/chart.h 1
Where we can handle the gestures:
\snippet ../examples/zoomlinechart/chart.cpp 1
Note that you will need to call grabGesture() to both QMainWindow and QChart.
