Showcases how to add zooming to a Android Chart Control using the RubberBandXyZoomModifier, part of the ChartModifier API. It allows zooming in to a particular chart area by selecting it with a rectangle, which can be drawn with a finger. ChartModifiers can be added to the ChartModifierCollection through the setChartModifiers() method.

Tips!

The RubberBandXyZoomModifier may be restricted in the X-Axis only or unbounded. It zooms to the exact rectangle you draw. The rectangle may be styled.

Also try to double-tap to zoom to extents. This feature is provided by the ZoomExtentsModifier.
