JavaScript/jQuery Chart - zoomAndPan

Configures zooming and panning.

Type:

Object

You can enable zooming and panning for the argument and value axes independently. Set the argumentAxis and valueAxis options to enable zooming, panning, or both for a specific axis.

Users can use the mouse and touch gestures to zoom and pan. The following table illustrates user interaction:

Device Zooming Gestures Panning Gestures
Touch-enabled Spread and pinch Vertical or horizontal drag
Mouse-equipped Mouse Wheel Vertical or horizontal drag

You can use the allowTouchGestures or allowMouseWheel option to disable touch or mouse support.

Users can also use the mouse to zoom the chart by selecting an area with the drag gesture. Refer the dragToZoom option for more information.

Zooming and panning are related to the visual/whole range concept. Refer to the Visual and Whole Ranges article for more information.
