The SplineLayer class represents spline layers. SplineLayer is a subclass of Layer.

In the current version of ChartDirector, SplineLayer is implemented as a special configuration of LineLayer.

SplineLayer objects are created by using XYChart.addSplineLayer.

Method	Inherited	Description
setTension	(Self)	Sets the tension to use when computing the spline curve.
setSymbolScale	LineLayer	Sets the size of the symbol for each data point (for creating bubble charts).
setGapColor	LineLayer	Sets the color and style of the line used for jumping across NoValue data points.
setImageMapWidth	LineLayer	Sets the effective width of the line used for producing image maps.
getLine	LineLayer	Retrieves an opaque LineObj representing a line in the line layer. The opaque LineObj is to be used in XYChart.addInterLineLayer for adding coloring between lines.
set3D	Layer	Sets the 3D depth of the layer, and the 3D gap between the current layer and the next layer.
setLineWidth	Layer	Sets the default line width of lines when drawing data sets on the layer.
setBorderColor	Layer	Sets the default border color and 3D raised effect when drawing data sets on the layer.
setLegendOrder	Layer	Sets the order of the data set names as appeared in the legend box.
setLegend	Layer	Sets the order of the data set names as appeared in the legend box.
setDataCombineMethod	Layer	Sets the method used to combine multiple data sets in a layer.
addDataSet	Layer	Adds a data set to the chart layer.
getDataSet	Layer	Gets the requested DataSet object.
addDataGroup	Layer	Open a new data group.
addExtraField	Layer	Adds an array of text to be used as an extra field in various places.
addExtraField2	Layer	Adds an array of numbers/dates to be used as an extra field in various places.
setUseYAxis	Layer	Determine the y-axis to use when drawing the data sets.
setUseYAxis2	Layer	Determine if the primary or secondary y-axis should be used when drawing the data sets.
setXData	Layer	Sets the x values of the data points in the data sets.
setXData2	Layer	Sets the x values of the data points in the data sets as evenly distributed in a range.
alignLayer	Layer	Aligns the layer with a data set of another bar chart layer in Side layout.
getXCoor	Layer	Gets the x pixel coordinate of a point given the x data value.
getYCoor	Layer	Gets the y pixel coordinate of a point given the y data value.
xZoneColor	Layer	Creates a x-zone color. A x-zone will change from one color to another depending on a threshold value on the x-axis.
yZoneColor	Layer	Creates a y-zone color. A y-zone will change from one color to another depending on a threshold value on the y-axis.
setDataLabelStyle	Layer	Enables data labels and sets their styles.
setDataLabelFormat	Layer	Sets the data label format.
addCustomDataLabel	Layer	Adds a custom data label to a data point.
setAggregateLabelStyle	Layer	Enables aggregate labels and sets their styles.
setAggregateLabelFormat	Layer	Sets the aggregate label format.
addCustomAggregateLabel	Layer	Adds a custom aggregate label to an aggregated object.
addCustomGroupLabel	Layer	Adds a custom data group label to object representing the group.
getImageCoor	Layer	Gets the image map coordinates of a data point as represented in the layer as HTML image map attributes.
getImageCoor2	Layer	Gets the image map coordinates of a region containing all data points at the given x-position as HTML image map attributes.
getHTMLImageMap	Layer	Generates an HTML image map for all data points as represented on the layer.
setHTMLImageMap	Layer	Override the default arguments used when generating HTML image map for the layer.
