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
an absolute coordinate to convert
the CoordinateCalculatorBase which will do the transformation
the expected ECoordinateMode of the converted point
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)
Calculates coordinate in pixels of the specified value in the vertical dimension. Uses the yCoordinateMode (or xCoordinateMode for vertical chart)
Returns annotation borders for the AdornerLayer which has the size of the whole canvas
flag to return x and y values in ascending order
Returns annotationBorders
flag to return x and y values in ascending order, where x1 <= x2 and y1 <= y2
Get svg for the adorner grip handles for standard annotations
the value to convert
the CoordinateCalculatorBase which will do the transformation
the ECoordinateMode to apply
the pixel coordinate
Converts a pixel coordinate back to a value
coordinate or dataValue to convert
the CoordinateCalculatorBase which will do the transformation
the ECoordinateMode to apply
the data-value or value
Transforms an absolute coordinates point to the corresponding value point. The value point has x and y converted accordingly to the the coordinate modes xCoordinateMode and yCoordinateMode
defines if the coordinates should be projected from the Canvas to SeriesViewRect
a point with coordinates ECoordinateMode
Returns the pixel X1 coordinate
the X CoordinateCalculatorBase which will do the transformation
the Y CoordinateCalculatorBase which will do the transformation
the pixel X1 coordinate
Returns the pixel X2 coordinate
the X CoordinateCalculatorBase which will do the transformation
the Y CoordinateCalculatorBase which will do the transformation
the pixel X2 coordinate
Returns the pixel Y1 coordinate
the X CoordinateCalculatorBase which will do the transformation
the Y CoordinateCalculatorBase which will do the transformation
the pixel Y1 coordinate
Returns the pixel Y2 coordinate
the X CoordinateCalculatorBase which will do the transformation
the Y CoordinateCalculatorBase which will do the transformation
the pixel Y2 coordinate
The name of the property which has changed
Called when the Dpi changes in the browser. This could be due to user zooming the browser, or changing DPI settings in Windows, or moving the browser containing SciChart to another monitor
The TDpiChangedEventArgs containing info about the Dpi Changed event
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
Gets the svg string for the adorner for standard annotations. Called by updateAdornerInner. Coordinates passed in are the top left and bottom right of the bounding box. To get the bounding coordinates in their original order call this.getAdornerAnnotationBorders(false, true);
Updates adorner layer for the annotation
the annotation absolute coordinates
