Zooming in React Chart component

02 Feb 2023 / 6 minutes to read

To get start quickly with React Chart Zooming and Panning, you can check on this video:

Enable Zooming

Chart can be zoomed in three ways.

  • Selection - By setting enableSelectionZooming property to true in zoomSettings, you can zoom the chart by using the rubber band selection.
  • Mousewheel - By setting enableMouseWheelZooming property to true in zoomSettings, you can zoomin and zoomout the chart by scrolling the mouse wheel.
  • Pinch - By setting enablePinchZooming property to true in zoomSettings, you can zoom the chart through pinch gesture in touch enabled devices.

Note: Pinch zooming is supported only in browsers that support multi-touch gestures. Currently IE11, Chrome and Opera browsers support multi-touch in desktop devices.

};

After zooming the chart, a zooming toolbar will appear with zoom,zoomin, zoomout, pan and reset buttons. Selecting the Pan option will allow to pan the chart and selecting the Reset option will reset the zoomed chart.

Modes

The mode property in zoomSettings specifies whether the c hart is allowed to scale along the horizontal axis or vertical axis. The default value of the mode is XY (both axis).

There are three types of mode.

  • X - Allows us to zoom the chart horizontally.
  • Y - Allows us to zoom the chart vertically.
  • XY - Allows us to zoom the chart both vertically and horizontally.

Toolbar

By default, zoomin, zoomout, pan and reset buttons will be displayed for zoomed chart. You can customize to show the desired options in the toolbar using the toolbarItems property. Also using the showToolbar property, you can show toolkit for zooming and panning the chart during initial rendering itself.
