The ViewRoundBase type exposes the following members.

Properties

	Name	Description
	AutoSizeMargins	Automatically size margins based on LegendBox position and size. This is a dependency property.
	Border	Border options
	GraphBackground	Gets or sets graph background fill. This is a dependency property. (Inherited from View2D)
	Margins	Gets or sets margins between control's edges and for example graph area borders in DIPs. This is a dependency property.
	ZoomScale	Current zooming scale. 1 is the deafult zoom that shows the circle at it's maximum size so that it just fills the view area reduced by the margins.

Methods

	Name	Description
	CoordsToUCValue(PointFloat, Boolean)	Convert absolute screen coordinates to relative unit circle coordinates.
	CoordsToUCValue(PointFloat, Boolean)	Convert absolute screen coordinates to relative unit circle coordinates. The given pointfloat is modified.
	Dispose	Release all resources used by this instance. (Inherited from ChartNode)
	FreeMarkersDrawData	Free marker draw data.
	GetChartDiameterAndCenter	Get Smith or Polar charts outer diameter and center point in screen coordinates.
	GetMarginsRect	Gets a rectangle defining the area inside margins in DIPs. (Inherited from View2D)
	ToString	Convert class description to string
	UCValueToCoord(PointFloat, Boolean)	Convert relative unit circle coordinates to absolute screen coordinates.
	UCValueToCoord(PointFloat, Boolean)	Convert relative unit circle coordinates to absolute screen coordinates. The given pointfloat is modified.
	UCValueToCoord(PointUnitCircle, Boolean)	Convert relative unit circle coordinates to absolute screen coordinates.
	WheelScrolled	Mouse wheel has been scrolled. (Overrides ViewBaseWheelScrolled(UserInteractiveDeviceEventArgs, LightningChart))
	Zoom	Zoom the chart in or out. If stop point X is greater than start point X, zooms in. If stop point X is less than start point X action follows RightToLeftZoom property.
	ZoomByFactor	Zoom by given factor and around given view center as DIP or screen coordinates.
	ZoomToFit	Zooms the view so that the data is visible at maximum possible size. Area is either the full drawing area inside Margins or are further limited by ZoomPadding, depending on case. For more information, see options at ZoomAreaRound.
	ZoomToLabelsArea	Zooms the round view so that labels area is fitted to area inside ZoomPadding. Publicly accessible via ZoomToFit(ZoomAreaRound) method and ZoomToData.

Events

	Name	Description
	BeforePanning	Panning is about to start.
	BeforeZooming	Zooming is about to start.
	MarginsChanged	Margins changed. (Inherited from ViewBase)
	Panned	Panning has ended.
	ValueChangedInternallyEvent	Value has changed internally by chart or by user manipulation of chart object. (Inherited from ChartNode)
	Zoomed	Zooming has ended.

Fields

	Name	Description
