AG Charts implements touch and multi-touch support, enabling interactivity across all devices.
Touch Options
All interactivity is available via touch input.
For example:
- Tap the series area to show tooltips and crosshairs.
- Tap or double-tap to toggle a legend item, reset zoom, or press any of the UI buttons.
- Any click and double-click events are also triggered by a tap or double-tap.
- Long tap to bring up the context menu.
- Drag to zoom the axes, pan a zoomed chart, or interact with annotations.
- Use two finger pinch gestures to zoom in or out of a chart, and two finger drag to pan a zoomed chart.
Single Finger Touch Dragging
By default, Single Finger Touch Drag events are handled like mouse drag events. To change the input handling behaviour of these events, use touch.dragAction.
touch: {
dragAction: 'hover',
}
In this example:
dragAction: 'none'disables the chart's Single Finger input handling, scrolling the entire page.dragAction: 'drag'emulates mouse dragging, updating the view's pan.dragAction: 'hover'emulates mouse movements, updating the tooltip & highlighted node.
When emulating mouse dragging, Touch event will page through if Zoom is disabled or if the chart cannot be panned.
Two Finger Zoom-Pan
By default, charts with the Zoom feature enabled still update the viewport's zoom and pan when using two fingers. To disable, use enableTwoFingerZoom: false.
Long Tap
Long Tapping the chart will expand the Context Menu, if available.
