setPolar: Set 'polar' of Echarts (For Radar Charts)

In madlogos/recharts2: An R Interface to ECharts3

Description

Set the polar coordinates of Echarts for radar charts.
When an echart object is generated, you can modify it by setting aesthetics using %>%.

Usage

setPolar(chart, polarIndex = NULL, center = c("50%", "50%"),
  radius = "75%", startAngle = 90, splitNumber = 5, boundaryGap = c(0,
  0), scale = FALSE, axisLine = NULL, axisLabel = NULL,
  splitLine = NULL, splitArea = NULL, type = c("polygon", "circle"),
  indicator = NULL, axisName = NULL, ...)

Arguments

chart	echarts object generated by echart or echartR
polarIndex	Integer vector. The index of the polar systems you want to set. Default NULL.
center	Vector of the x, y position of the polar center. Could be numeric or character (percent form) vectors of length 2. Default c('50%', '50%').
radius	The radius of the polar system, could be numeric or character (percent form). Default '75%'.
startAngle	Numeric (-180 ~ 180). The start angle. Default 90.
splitNumber	Numeric. The number of sections to divide. Default 5.
boundaryGap	Numeric vector of length 2. The gapping policy of the axis. Default c(0, 0).
scale	Logical. Whether to ignore zero and zoom toward the range of _min and _max.
axisLine	List. Axis line styles. You can set its show, onZero, lineStyle features. Default list(show=TRUE).
axisLabel	List. Axis label styles. You can set its show, rotate, margin, clickable, formatter, textStyle features. Default list(show=FALSE).
splitLine	List. Split line styles. You can set its show, lineStyle features. Default list(show=TRUE).
splitArea	List. Split area styles. You can set its show, onGap, areaStyle features. Default list(show=TRUE).
type	Character, 'polygon' or 'circle'. The type of the polar shape. Default 'polygon'.
indicator	List. The radar indicator and labels. The basic structure is list(list(text='...', min=..., max=..., axisLabel=list(...)), list(text='...', min=..., max=...), list(...), ...). Default is empty.
axisName	List. The name of the axis. You can set its show, formatter, textStyle features. Default list(show=TRUE, formatter=NULL, textStyle= list(color='#333')).
...	Elipsis

Value

A modified echarts object
