PolarChart.addSplineAreaLayer

ChartDirector 7.0 (Python Edition)

Usage

addSplineAreaLayer(data [, color [, name ]])

Description

Adds a polar spline area layer to the polar chart.

In a polar spline area layer, the data points are connected together using cardinal spline curves (as opposed to straight lines). The "tension" of the curve can be configured using PolarSplineAreaLayer.setTension.

Arguments

Argument	Default	Description
data	(Mandatory)	An array of numbers representing the data points in the layer.
color	-1	The color to draw the spline area. -1 means that the color is automatically selected from the palette.
name	""	The name of the layer. The name will be used in the legend box, if one is available. An empty string means the layer has no name.

Return Value

A PolarSplineAreaLayer object representing the chart layer created.
