Usage

dyCallbacks(dygraph, clickCallback = NULL, drawCallback = NULL,
  highlightCallback = NULL, pointClickCallback = NULL,
  underlayCallback = NULL, unhighlightCallback = NULL,
  zoomCallback = NULL, drawHighlightPointCallback = NULL,
  drawPointCallback = NULL, annotationClickHandler = NULL,
  annotationMouseOverHandler = NULL, annotationMouseOutHandler = NULL,
  annotationDblClickHandler = NULL)

Arguments

`dygraph`	Dygraph to add callbacks to
`clickCallback`	A function to call when the canvas is clicked.
`drawCallback`	When set, this callback gets called every time the dygraph is drawn. This includes the initial draw, after zooming and repeatedly while panning.
`highlightCallback`	When set, this callback gets called every time a new point is highlighted.
`pointClickCallback`	A function to call when a data point is clicked. and the point that was clicked.
`underlayCallback`	When set, this callback gets called before the chart is drawn.

`zoomCallback`	A function to call when the zoom window is changed (either by zooming in or out).
`drawHighlightPointCallback`	Draw a custom item when a point is highlighted. Default is a small dot matching the series color. This method should constrain drawing to within pointSize pixels from (cx, cy)
`drawPointCallback`	Draw a custom item when drawPoints is enabled. Default is a small dot matching the series color. This method should constrain drawing to within pointSize pixels from (cx, cy).
`annotationClickHandler`	JavaScript function to call when an annotation is clicked. This can also be specified on a per-annotation basis.
`annotationMouseOverHandler`	JavaScript function to call when the mouse hovers over an annotation. This can also be specified on a per-annotation basis.
`annotationMouseOutHandler`	JavaScript function to call when the mouse exits an annotation. This can also be specified on a per-annotation basis.
