JavaScript/jQuery Chart - zoomAndPan
You can enable zooming and panning for the argument and value axes independently. Set the argumentAxis and valueAxis properties 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 property 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 property 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.
