Charts

Zooming and Scrolling

Documentation

In this demo, the visualRange option is used to zoom the chart initially. The zoomAndPan.argumentAxis option allows you to zoom and scroll the argument axis at runtime.

Zooming and scrolling are available on mouse-equipped and touch-enable devices: you can use the mouse wheel/spread and pinch gestures to zoom, and the scrollbar/drag gesture to scroll.
