Arguments

x	Input table containing survey responses in 4 columns At what price would you consider this product/brand to be 1) Very cheap, 2) Cheap, 3) Expensive, 4) Very expensive.
check.prices.ordered	Check that prices supplied in the first 4 columns of x are supplied in increasing order. For backwards compatibility this is off by default.
weights	A numeric vector with length equal to the number of rows in x. They are applied whem computing the proportions of respondents for each question
likelihood.scale	Used in NSM calculation to convert likelihood scale to probabiliy. Default scale assumes a 7 point scale.
output	Type of data to show in the chart. One of "Attitude of respondents", "Likelihood to buy" and "Revenue".
resolution	Numeric; controls the intervals (in terms of price) between which "Proportion of respondents" is computed. For example, set to 0.1, to evaluate proportions every 10 cents. By default, we use observed values.
colors	Character; a vector containing one or more colors specified as hex codes.
line.type	Character; one of 'solid', 'dot', 'dashed'.
line.thickness	Thickness, in pixels, of the series line
currency	Character; Currency symbol to prepend to the intersection labels. These will also be used to set the default prefix to the x tick labels and hovertext.
global.font.family	Character; font family for all occurrences of any font attribute for the chart unless specified individually.
global.font.color	Global font color as a named color in character format (e.g. "black") or an a hex code.
title.font.size	Integer; Title font size; default = 10.
subtitle.font.size	Integer; subtitle font size
footer.font.size	Integer; footer font size
legend.font.size	Integer; Legend font size.
hovertext.font.size	Font size of hover text.
y.title.font.size	Integer; y-axis title font size
x.title.font.size	Integer; x-axis title font size
y.tick.font.size	Integer; y-axis tick label font size
x.tick.font.size	Integer; x-axis tick label font size
data.label.font.size	Integer; Font size for data label.px.
hovertext.font.family	Font family of hover text.
y.title.font.family	Character; y-axis title font family
y.title.font.color	y-axis title font color as a named color in character format (e.g. "black") or a hex code.
y.tick.font.family	Character; y-axis tick label font family
y.tick.font.color	y-axis tick label font color as a named color in character format (e.g. "black") or an a hex code.
x.title	Character, x-axis title; defaults to chart input values; to turn off set to "FALSE".
x.tick.prefix	x-axis tick label prefix
x.hovertext.format	A string representing a d3 formatting code. See https://github.com/mbostock/d3/wiki/Formatting#numbers
y.title	Character, y-axis title; defaults to chart input values; to turn off set to "FALSE".
y.tick.format	A string representing a d3 formatting code. See https://github.com/d3/d3/blob/master/API.md#number-formats-d3-format
intersection.show	Logical; Whether to show labels to the intersection points of the lines.
intersection.arrow.color	Color of the arrows to the intersection points.
intersection.arrow.size	Size of the arrows to the intersection points.
intersection.arrow.width	Width of the arrow heads.
intersection.arrow.length	Scaling factor controlling length of arrows.
intersection.arrow.standoff	Distance between arrowhead and intersection point.
intersection.label.font.family	Character; intersection.label font family
intersection.label.font.color	intersection.label font color as a named color in character format (e.g. "black") or an a hex code.
intersection.label.font.size	Integer; intersection label font size
intersection.label.decimals	Integer; number of decimals to show on intersection label.
intersection.label.wrap	Logical; whether the intersection label text should be wrapped.
intersection.label.wrap.nchar	Number of characters (approximately) in each line of the intersection label when intersection.label.wrap TRUE.
font.units	One of "px" of "pt". By default all font sizes are specified in terms of pixels ("px"). But changing this to "pt" will mean that the font sizes will be in terms points ("pt"), which will be consistent with font sizes in text boxes.
...	Other charting parameters passed to Line.
