  • MinZoom: A property of type Size which gets or sets the minimum allowed zoom value.

  • PanOffset: A property of type Point which gets or sets the horizontal and vertical offset of the viewport when the chart is zoomed.

  • Zoom: A property of type Size which gets or sets the current scale factor of the charting component.

Styling properties

  • DragZoomBorderStyle: A property of type Style which gets or sets the visual appearance of the DragZoomBorder element. This component is visualized when the user zoom-in the plot area with drag-zooming. The property expects a Style with its TargetType set to System.Windows.Controls.Border.

  • VerticalZoomRangeEnd: A property of type Double which gets or sets where the vertical zoom range will end. The valid values are from 0 to 1.

Events

  • PanOffsetChanged: An event which occurs when the chart's pan offset gets changed. The event will be fired only if ChartPanAndZoomBehavior is added in the Behaviors collection of the chart.

    • NewPanOffset: A property of type Point which gets the new pan offset.
    • PreviousPanOffset: A property of type Point which gets the previously applied pan offset.
  • ZoomChanged: An event which occurs when the chart's zoom gets changed. The event will be fired only if ChartPanAndZoomBehavior is added in the Behaviors collection of the chart.

    The event arguments are passed with the ChartZoomChangedEventArgs class which provides the following properties:
