Class FibonacciArc

Draws a trend line between two control points, followed by multiple arcs intersecting the line at levels 38.2%, 50.0%, 61.8% and 100%. The percentages are based on the length of the line. The arcs are centered at the second control point.

    Returns void

onDrawingToolMoved

  • Event that triggers when drawing tool's position has been changed either by dragging it or in code.

    Parameters

    • handler: Handler<DrawingToolMovedEvent>

      Event handler containing 'startX' and 'startY' parameters for the first control point position, and respectively 'endX' and 'endY' parameters for the second control point position.

    Returns void

onPointerDown

  • Event that triggers when pointer is pressed down on top of the drawing tool.

    Parameters

    • handler: Handler<PointerDownEvent>

      Event handler containing the following parameters:

      -'xPosition' and 'yPosition' parameters return the current cursor position in axis values.

      -'xPositionClient' and 'yPositionClient' return the current cursor position in client coordinates (zero equals top-left corner).

      -'drawingTool' gets the drawing tool instance.

      -'isControlPoint' tells if the event was triggered by one of the drawing tool's control points.

      -'button' indicates the pressed mouse button.

    Returns void

onPointerEnter

  • Event that triggers when pointer is moved onto the drawing tool.

    Parameters

    • handler: Handler<PointerEnterEvent>

      Event handler containing the following parameters:

      -'xPosition' and 'yPosition' parameters return the current cursor position in axis values.

      -'xPositionClient' and 'yPositionClient' return the current cursor position in client coordinates (zero equals top-left corner).

      -'drawingTool' gets the drawing tool instance.

      -'isControlPoint' tells if the event was triggered by one of the drawing tool's control points.

    Returns void

onPointerLeave

  • Event that triggers when pointer is moved away from the drawing tool.

    Parameters

    • handler: Handler<PointerLeaveEvent>

      Event handler containing the following parameters:

      -'xPosition' and 'yPosition' parameters return the current cursor position in axis values.

      -'xPositionClient' and 'yPositionClient' return the current cursor position in client coordinates (zero equals top-left corner).

      -'drawingTool' gets the drawing tool instance.

      -'isControlPoint' tells if the event was triggered by one of the drawing tool's control points.

    Returns void

onPointerUp

  • Event that triggers when pointer is released on top of the drawing tool.

    Parameters

    • handler: Handler<PointerUpEvent>

      Event handler containing the following parameters:

      -'xPosition' and 'yPosition' parameters return the current cursor position in axis values.

      -'xPositionClient' and 'yPositionClient' return the current cursor position in client coordinates (zero equals top-left corner).

      -'drawingTool' gets the drawing tool instance.

      -'isControlPoint' tells if the event was triggered by one of the drawing tool's control points.

      -'button' indicates the released mouse button.

    Returns void

setFillEnabled

  • Set whether areas between the Fibonacci Arc lines are colored or not.

    Parameters

    • fillEnabled: boolean

      Set true to enable colors.

    Returns void

setLineColor

  • Sets the color of the Fibonacci Arc lines.

    Parameters

    • newColor: string

      New line color as string, should be in HEX format e.g. #FFFFFF.

    Returns void

setLineWidth

  • Sets the width of the Fibonacci Arc lines.

    Parameters

    • newWidth: number

      New line width.

    Returns void

setMagnetic

  • Sets whether the drawing tool should automatically snap to OLHC-data points.

    Parameters

    • isMagnetic: boolean

      Set true to enable snapping to data points.

    Returns void

updatePosition

  • Updates the drawing tool based on the control points' locations.

    -If Magnetic Line is enabled (via setMagnetic), the line gets Y-values automatically based on the closest Close-value.

    Parameters

    • startX: number

      Starting point X location.

    • startY: number

      Starting point Y location.

    • endX: number

      End point X location.

    • endY: number
