dyHighlight: dygraph series mouse-over highlighting

In dygraphs: Interface to 'Dygraphs' Interactive Time Series Charting Library

Description

Configure options for data series mouse-over highlighting. Note that highlighting is always enabled for dygraphs so this function is used to customize rather than enable highlighting.

Usage

dyHighlight(dygraph, highlightCircleSize = 3,
  highlightSeriesBackgroundAlpha = 0.5, highlightSeriesOpts = list(),
  hideOnMouseOut = TRUE)

Arguments

dygraph	Dygraph to configure highlighting behavior for.
highlightCircleSize	The size in pixels of the dot drawn over highlighted points.
highlightSeriesBackgroundAlpha	Fade the background while highlighting series. 1=fully visible background (disable fading), 0=hidden background (show highlighted series only).
highlightSeriesOpts	When set, the options from this list are applied to the series closest to the mouse pointer for interactive highlighting. Example: list(strokeWidth = 3). See the documentation on dySeries for additional details on options that can be set.
hideOnMouseOut	Whether to hide the highlighting effects when the mouse leaves the chart area. Note that this also affects the hiding of the dyLegend on mouse out.

Value

A dygraph with customized highlighting options

Note

See the online documentation for additional details and examples.
