LineLayer.setSymbolScale

`[C#]`	`public void setSymbolScale(double[] zDataX [, int scaleTypeX [, double[] zDataY [, int scaleTypeY ]]]);`
`[VB]`	`Public Sub setSymbolScale(zDataX As Double() [, scaleTypeX As Integer [, zDataY As Double() [, scaleTypeY As Integer ]]])`

Sets the size of the symbol for each data point (for creating bubble charts).

One common usage for this method is to draw circle symbols of different sizes at each data points, creating a bubble chart.

This method supports any valid data symbols. You can create bubble charts with square bubbles, or even custom data symbols. Also, this method supports independent x and y direction sizing, so you can create bubbles elliptical in shape, and use the horizontal and vertical radius to represent different data.

ChartDirector supports specifying sizes as pixels or in axis scale. The unit is specified by using the following predefined constants.

Constant	Value	Description
PixelScale	0	The unit is measured in pixels.
XAxisScale	1	The unit is measured in x-axis scale.
YAxisScale	2	The unit is measured in y-axis scale.

Argument	Default	Description
zDataX	(Mandatory)	The sizes of the symbols at the x-axis direction, expressed using the unit defined by the scaleTypeX argument.
scaleTypeX	PixelScale	The unit for zDataX, which must be one of the predefined constants in the table above.
zDataY	[Empty_Array]	The sizes of the symbols at the y-axis direction, expressed using the unit defined by the scaleTypeY argument. An empty array means the sizes at the y-axis direction are the means as the sizes at the x-axis direction.
scaleTypeY	PixelScale	The unit for zDataY, which must be one of the predefined constants in the table above.
