lineopt_ist: Line options

In JohnCoene/chartist: chartist.js in R

Description

Pass options to line type.

Usage

lineopt_ist(p, name, fillHoles = FALSE, showPoint = TRUE,
  showArea = FALSE, showLine = TRUE, areaBase = 0,
  lineSmoothing = "simple", fullWidth = TRUE, distributeSeries = FALSE,
  width, height, low, high, chartPadding, ...)

Arguments

p	a chartist object.
name	name the serie, see details (optional).
fillHoles	whether to fill missing data, defaults to FALSE.
showPoint	whether to show points, defaults to TRUE.
showArea	turn line chart into area chart, defaults to FALSE.
showLine	set FALSE to hide line.
areaBase	base for the chart, defaults to 0.
lineSmoothing	defaults to simple, can take an integer, step, none or an htmlwidgets javascript function (class JS_EVAL).
fullWidth	When set to true, the last grid line on the x-axis is not drawn and the chart elements will expand to the full available width of the chart. For the last label to be drawn correctly you might need to add chart padding or offset the last label with a draw event handler.
distributeSeries	distributed serie along x axis only works for 1 serie, defaults to FALSE.
width	set fixed width in pixels or percent (i.e.: 300px, 70%).
height	set fixed height in pixels or percent (i.e.: 300px, 70%).
low	lower bound of value.
high	higher bound of value.
chartPadding	padding around chart div.
...	additional options.

Examples

mtcars %>%
   chart_ist(x = mpg, type = "line") %>%
   add_ist(disp) %>%
   lineopt_ist(showArea = TRUE, showLine = FALSE, showPoint = FALSE)

mtcars %>%
   chart_ist(x = mpg, type = "line") %>%
   add_ist(disp) %>%
   lineopt_ist(lineSmoothing = "step", showLine = TRUE, showPoint = FALSE)

mtcars %>%
   chart_ist(x = mpg, type = "line") %>%
   add_ist(disp, name = "disp") %>%
   add_ist(hp, name = "hp") %>%
   lineopt_ist(name = "disp", lineSmoothing = "none") %>%
   lineopt_ist(name = "hp", showArea = TRUE, showPoint = FALSE)

mtcars %>%
   chart_ist(qsec) %>%
   add_ist(mpg) %>%
   lineopt_ist(lineSmoothing = htmlwidgets::JS("
       Chartist.Interpolation.cardinal({tension: 0.2})"))
