getSizeCoefficient

public double getSizeCoefficient()

Returns the size coefficient of chart items. The value is expressed as a coefficient of the available range.

Returns:

the coefficient.

Since:

8.0

See Also:

setSizeCoefficient(double)

setSizeCoefficient

public void setSizeCoefficient(double sizeCoefficient)

Sets the size coefficient of the bubbles. The value is expressed as a coefficient of the available range. Allowed value are between 0 and 1. This property works only with the chart type XYStyle.BUBBLE. To set the shape size of scatter chart please use thisAbstractPlot.setItemShape(ItemShape).
