Calculates if the annotation is hovered with the specified args
Called internally. Send a click to the annotation if the point is in bounds, raising the clicked event and optionally selecting the annotation.
Called internally. Select the annotation if the point is in bounds. Does not raise the clicked event
Converts an absolute coordinate to a value which could be in form of DataValue, Pixel, or Relative coordinate

the data-value, pixel, or relative value accordingly to the coordinateMode
Deletes native (WebAssembly) memory used by this type, after which it cannot be used.
Calculates coordinates in pixels of the specified Point. Uses the xCoordinateMode (or yCoordinateMode for vertical chart)
Calculates coordinates in pixels of the specified Point. Uses the xCoordinateMode (or yCoordinateMode for vertical chart)

Sends hover/leave action to the annotation
The name of the property which has changed
Internal use. If isHidden,x1,y1 have change since suspendInvalidate was called, call invalidateParent
Sets annotationBorders For renderContext annotations it is scaled and for SVG annotations it is not For example if we have a macbook with retina display and canvas.width = 1600px, canvas.height = 1200px, canvas.style.width = 800px, canvas.style.height = 600px If we have BoxAnnotation (renderContext) which takes 50% width and height, located in the left-top corner it should have annotationBorders as follows x1 = 0, x2 = 800, y1 = 0, y2 = 600 But if we have CustomAnnotation (SVG) which takes 50% width and height, located in the left-top corner it should have annotationBorders as follows x1 = 0, x2 = 400, y1 = 0, y2 = 300
Internal use. Captures the state of isHidden,x1,y1 and prevents invalidateParent being called on change to these properties
the annotation absolute coordinates
Generated using TypeDoc
The NativeTextAnnotation provides an Annotation which draws a text at specific x1 y1 over the SciChartSurface
To add a NativeTextAnnotation to a SciChartSurface, use the following code:
const sciChartSurface: SciChartSurface; const textAnnotation = new NativeTextAnnotation( { x1: 1, y1: 3, color: "#FF000077", text: "Hello SciChart"}); sciChartSurface.annotations.add(textAnnotation);Uses the fast WebGL/WebAssembly {@link WebGL2RenderingContext} for rendering
