RadialAxisPlot

RadialAxisPlot[{y₁,y₂,…,y_n}]

generates a radial axis plot where the y_i are displayed on radial axes equally spaced around the origin.

RadialAxisPlot[{data₁,data₂,…}]

plots several datasets data_i on the axes.

Details and Options

RadialAxisPlot is also known as radar plot, spider chart or star plot.
RadialAxisPlot is used to visualize multidimensional data by mapping each dimension to an axis, creating a unique shape. The shapes for different data points can then be compared with each other.

The data values y_i can be given in the following forms:
y_i a real-valued number

Quantity[y_i,unit] a quantity with a unit
Values y_i that are not of the forms previously shown are taken to be missing and are not shown.
The data_i have the following forms and interpretations:

	<\|"k₁"y₁,"k₂"y₂,…\|>	values {y₁,y₂,…}
	{y₁"lbl₁",y₂"lbl₂",…}, {y₁,y₂,…}{"lbl₁","lbl₂",…}	values {y₁,y₂,…} with labels {lbl₁,lbl₂,…}
	SparseArray	values as a normal array
	TimeSeries,EventSeries,…	values from time series data
	QuantityArray	magnitudes
	WeightedData	unweighted values

The following wrappers w can be used for the data_i:

	Annotation[data_i,label]	provide an annotation for the data
	Button[data_i,action]	define an action to execute when the data is clicked
	Callout[data_i,label]	label the data with a callout
	Callout[data_i,label,pos]	place the callout at relative position pos
	EventHandler[data_i,events]	define a general event handler for the data
	Hyperlink[data_i,uri]	make the data a hyperlink
	Labeled[data_i,label]	label the data
	Labeled[data_i,label,pos]	place the label at relative position pos
	Legended[data_i,label]	identify the data in a legend
	PopupWindow[data_i,cont]	attach a popup window to the data
	StatusArea[data_i,label]	display in the status area on mouseover
	Style[data_i,styles]	show the data using the specified styles
	Tooltip[data_i,label]	attach a tooltip to the curve

Wrappers w can be applied at multiple levels:

	{…,w[y_i],…}	wrap the value y_i in data
	{…,w[{x_i,y_i}],…}	wrap the point {x_i,y_i}
	w[data_i]	wrap the data
	w[{data₁,…}]	wrap a collection of data_i
	w₁[w₂[…]]	use nested wrappers

Callout, Labeled and Placed can use the following positions pos:

	Automatic	automatically placed labels
	Above, Below, Before, After	positions around the curve
	"Inside","Outside"	relative to the point along the axis
	{pos,epos}	epos in label placed at relative position pos of the curve

RadialAxisPlot has the same options as Graphics, with the following additions and changes: [List of all options]

Axes	True	whether to draw axes
AxesOrigin	Automatic	where to position the axes
ColorFunction	Automatic	how to determine the coloring of lines
ColorFunctionScaling	True	whether to scale arguments to ColorFunction
Filling	True	filling under each line
FillingStyle	Automatic	style to use for filling
GridLines	Automatic	whether to draw grid lines

ScalingFunctions	None	how to scale individual coordinates

The axes are arranged clockwise starting from the positive y axis.
By default, all the axes have the same plot range.
With AxesAutomatic, only the first axis will be shown if all of the axes have the same scale and plot range. If there are any differences, all the axes will be shown.
With the default setting PlotRangeAutomatic, all the axes use the same plot range.
PlotRangeAll uses a different plot range for each axis.
Options that apply to each axis, such as Axes, Ticks and PlotRange, can take the following forms:

	s	use setting s for each axis
	{s₁,…,s_n}	use per-axis setting s₁ for the first axis, etc.
	{…,pats,…}	use setting s for axis positions matching pattern pat

With the form {…,pats,…}, pat can be any pattern. The first pattern that matches an axis position will be used. If no pattern matches an axis position, the default value is used.
The arguments supplied to ColorFunction are y₁,y₂,…,y_n. By default, the color function arguments are scaled per axis to be between 0 and 1.
Possible settings for PlotLayout that show multiple points in a single plot panel include:
"Overlaid" show all the data overlapping

"Stacked" accumulate the data

"Percentile" accumulate and normalize the data
Possible settings for PlotLayout that show a single point in multiple plot panels include:

	"Column"	use separate curves in a column of panels
	"Row"	use separate curves in a row of panels
	{"Column",k},{"Row",k}	use k columns or rows
	{"Column",UpTo[k]},{"Row",UpTo[k]}	use at most k columns or rows
