dygraph interactive range selection and zooming
Add a range selector to the bottom of the chart that allows users to pan and zoom to various date ranges.
dyRangeSelector(dygraph, dateWindow = NULL, height = 40, fillColor = " #A7B1C4", strokeColor = "#808FAB", keepMouseZoom = TRUE, retainDateWindow = FALSE)
dygraph |
Dygraph to add range selector to |
dateWindow |
Initially zoom in on a section of the graph. Is a two
element vector [earliest, latest], where earliest/latest objects
convertible via |
height |
Height, in pixels, of the range selector widget. |
fillColor |

strokeColor |
The range selector mini plot stroke color. This can be of the form "#AABBCC" or "rgb(255,100,200)" or "yellow". You can also specify "" to turn off stroke. |
keepMouseZoom |
Keep mouse zoom when adding a range selector |

A dygraph that displays a range selector
See the online documentation for additional details and examples.
Shiny applications can respond to changes in the dateWindow
via a special date window shiny input value. For example, if the
output id of a dygraph is 'series' then the current date window
can be read from input$series_date_window as an array of
two date values (from and to).
