The end-user experience is greatly enhanced by including a set of user interaction features such as zooming and panning, crosshair, trackball, drill-down, events, and tooltip. You can configure these interactive chart features using the built-in APIs.


Visualize data points in any region of the chart by zooming the region.


Zooming mode

Zooming direction

Zoom the chart along the horizontal axis, vertical axis, or both axes.

Zoom toolbar
