Create a Line Chart

Usage

v_line(
  vc,
  mapping = NULL,
  data = NULL,
  name = NULL,
  line = list(style = list(curveType = "linear", lineDash = 0, stroke = NULL)),
  point = list(visible = FALSE),
  ...,
  serie_id = NULL,
  data_id = NULL
)

Arguments

vc: A chart initialized with vchart().
mapping: Default list of aesthetic mappings to use for chart.
data: Default dataset to use for chart. If not already a data.frame, it will be coerced to with as.data.frame.
name: Name for the serie, only used for single serie (no color/fill aesthetic supplied).
line: Line's options, such as curve interpolation type, see online documentation
point: Options for showing points on lines or not.
...: Additional parameters for the serie.
data_id, serie_id: ID for the data/serie, can be used to further customize the chart with v_specs().

Value

A vchart() htmlwidget object.

Examples


library(vchartr)

# Basic Line Chart
vchart(eco2mix) %>% 
  v_line(aes(date, solar))


# Two lines
vchart(tail(eco2mix, 30), aes(date)) %>% 
  v_line(aes(y = solar)) %>% 
  v_line(aes(y = wind))


# Line chart with discrete x axis
vchart(data.frame(month = month.abb, value = sample(1:50, 12))) %>% 
  v_line(aes(month, value))


# Stroke color 
vchart(data.frame(month = month.abb, value = sample(1:50, 12))) %>% 
  v_line(
    aes(month, value),
    line = list(style = list(stroke = "firebrick"))
  )


# Smooth Line Chart
vchart(data.frame(month = month.abb, value = sample(1:50, 12))) %>% 
  v_line(
    aes(month, value), 
    line = list(style = list(curveType = "monotone"))
  )


# Step Line Chart
vchart(data.frame(month = month.abb, value = sample(1:50, 12))) %>% 
  v_line(
    aes(month, value),
    line = list(style = list(curveType = "stepAfter"))
  )


# Dash array 
vchart(data.frame(month = month.abb, value = sample(1:50, 12))) %>% 
  v_line(
    aes(month, value),
    line = list(style = list(lineDash = c(10, 10)))
  )


# Multiple lines
vchart(eco2mix_long) %>% 
  v_line(aes(date, production, color = source))
