Zooming and Panning

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.

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 of Zooming

The mode property in zoomSettings specifies whether the chart 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.

Crosshair

Crosshair has a vertical and horizontal line to view the value of the axis at mouse or touch position.

Enable Crosshair

Crosshair lines can be enabled by using enable property in the crosshair. Likewise tooltip label for an axis can be enabled by using enable property of crosshairTooltip in the corresponding axis.

Customization

The fill and textStyle prop property of the crosshairTooltip is used to customize the background color and font style of the crosshair label respectively. Color and width of the crosshair line can be customized by using the line property in the crosshair.

Note: To use crosshair feature, we need to inject Crosshair module Chart.Inject(Crosshair) method.

Trackball

Trackball is used to track a data point closest to the mouse or touch position. Trackball marker indicates the closest point and trackball tooltip displays the information about the point. To use trackball feature, we need to inject Crosshair module and Tooltip module using Chart.Inject(Crosshair, Tooltip).

Trackball can be enabled by setting the enable property of the crosshair to true and shared property in tooltip to true in chart.

DragXY, DragX and DragY

To fetch a collection of data under a particular region, you have to set selectionMode as DragXY.

  • DragXY - Allow us to select data with respect to both horizontal and vertical axis.
  • DragX - Allow us to select data with respect to horizontal axis.
  • DragY - Allow us to select data with respect to vertical axis.

The selected data’s are returned as an array collection in the dragComplete event.
