dygraph interactive range selection and zooming

Description

Add a range selector to the bottom of the chart that allows users to pan and zoom to various date ranges.

Usage

dyRangeSelector(
  dygraph,
  dateWindow = NULL,
  height = 40,
  fillColor = " #A7B1C4",
  strokeColor = "#808FAB",
  keepMouseZoom = TRUE,
  retainDateWindow = FALSE
)

Arguments

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 as.POSIXct.

height

Height, in pixels, of the range selector widget.

fillColor

The range selector mini plot fill color. This can be of the form "#AABBCC" or "rgb(255,100,200)" or "yellow". You can also specify "" to turn off fill.

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

retainDateWindow

Whether to retain the user's current date window (zoom level) when updating an existing dygraph with new data and/or options.

Value

A dygraph that displays a range selector

Note

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).

Examples

library(dygraphs)

dygraph(nhtemp, main = "New Haven Temperatures") %>% 
  dyRangeSelector()   
 
dygraph(nhtemp, main = "New Haven Temperatures") %>% 
  dyRangeSelector(dateWindow = c("1920-01-01", "1960-01-01"))   
    
dygraph(nhtemp, main = "New Haven Temperatures") %>% 
  dyRangeSelector(height = 20, strokeColor = "")
