vchart: Create interactive charts with VChart

In vchartr: Interactive Charts with the 'JavaScript' 'VChart' Library

Create interactive charts with VChart

Description

VChart is a charting component library, see more about it here : https://www.visactor.io/vchart.

Usage

vchart(
  data = NULL,
  mapping = NULL,
  ...,
  width = NULL,
  height = NULL,
  elementId = NULL
)

Arguments

data	Can be a data.frame if function used with other layers functions or a list of parameters for configuring a chart.
mapping	Default list of aesthetic mappings to use for chart, only used if data is a data.frame.
...	Additional parameters.
width	Fixed width for widget (in css units). The default is NULL, which results in intelligent automatic sizing based on the widget's container.
height	Fixed height for widget (in css units). The default is NULL, which results in intelligent automatic sizing based on the widget's container.
elementId	Use an explicit element ID for the widget (rather than an automatically generated one). Useful if you have other JavaScript that needs to explicitly discover and interact with a specific widget instance.

Value

A vchart() htmlwidget object.

Note

This function allow you to use JavaScript function VChart directly, see https://www.visactor.io/vchart/option/ for how to specify options.

Examples

library(vchartr)

# Use JS syntax to construct chart
vchart(
  type = "line",
  data = list(
    list(
      values = list(
        list(month = "January", value = 4.3),
        list(month = "February", value = 4.6),
        list(month = "March", value = 7.4),
        list(month = "April", value = 10.7),
        list(month = "May", value = 14.3),
        list(month = "June", value = 17.7),
        list(month = "July", value = 19.8),
        list(month = "August", value = 19.4),
        list(month = "September", value = 16.4),
        list(month = "October", value = 12.6),
        list(month = "November", value = 7.9),
        list(month = "December", value = 4.8)
      )
    )
  ),
  xField = "month",
  yField = "value",
  crosshair = list(
    xField = list(visible = TRUE)
  )
)

# or use R API
vchart(meteo_paris) %>%
  v_line(aes(month, temperature_avg)) %>%
  v_specs(
    crosshair = list(
      xField = list(visible = TRUE)
    )
  )

# or
vchart(meteo_paris, aes(month, temperature_avg)) %>%
  v_line() %>%
  v_specs(
    crosshair = list(
      xField = list(visible = TRUE)
    )
  )

# or
vchart() %>%
  v_line(aes(month, temperature_avg), data = meteo_paris) %>%
  v_specs(
    crosshair = list(
      xField = list(visible = TRUE)
