Charts

Zooming and Scrolling

Documentation

The Chart widget includes the zooming and scrolling capabilities. In this example, the Chart is initially zoomed. To enable scrolling, the scrollingMode option is set to «all». This setting enables scrolling both on mouse-equipped and touch-enable devices. To scroll the Chart, drag the chart’s plot or use the scrollbar at the top.
