vchartr (version 0.1.4)

vchart: 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
)

Value

A vchart()

htmlwidget object.

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.

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 = "December", value = 4.8)
      )
    )
  ),
  xField = "month",
  yField = "value",
  crosshair = list(
    xField = list(visible = TRUE)
  )
)

# or use R API

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

# or
