public class BubbleChart
extends XYDataChart

Bubble chart. A bubble chart is plotted on a RectangularCoordinate system and at each (x, y) point, there can be an associated "value". A "bubble" is drawn for each such data point, and the size of the "bubble" is proportional to the value. However, the size of the "bubble" can be controlled by setting a "multiplication factor" via setBubbleSize(double).

Internally, the "bubble" is an instance of the PointSymbol but, it may not be directly customized unless necessary.

A VisualMap is automatically created unless you set it explicitly to null via XYDataChart.setVisualMap(VisualMap).

Constructor Details

BubbleChart

public BubbleChart(AbstractDataProvider<?> xData,
 AbstractDataProvider<?> yData)

Constructor.

Parameters:

xData - Data for X axis.

yData - Data for Y axis.

Method Details

encodeJSON

public void encodeJSON(StringBuilder sb)

Description copied from interface: ComponentProperty

Encode the JSON string with the properties of this.

Specified by:

encodeJSON in interface ComponentProperty

Overrides:

encodeJSON in class Chart

Parameters:

sb - Encoded JSON string to be appended to this.

setBubbleSize

public void setBubbleSize(double multiplicationFactor)

Set the bubble size.

Parameters:

multiplicationFactor - This factor will multiply value at each data point to determine the size of the bubble.

setValuePrefix

public void setValuePrefix(String valuePrefix)

Set a prefix text to the value when the tooltip is displayed for the bubble.

Parameters:

valuePrefix - Prefix text.

setValueSuffix

public void setValueSuffix(String valueSuffix)

Set a suffix text to the value when the tooltip is displayed for the bubble.

Parameters:

valueSuffix - Suffix text.

getPointSymbol

public PointSymbol getPointSymbol(boolean create)

Get the PointSymbol that represents the "bubble".

Parameters:

create - Whether to create it if not exists or not.

Returns:

The instance of the current PointSymbol or newly created instance if requested.

setPointSymbol

public void setPointSymbol(PointSymbol pointSymbol)

Set a different PointSymbol that represents the "bubble". If set via this method, "bubble size" will no more be controlled automatically unless set it again via the setBubbleSize(double) method.

Parameters:

pointSymbol - An instance of the PointSymbol.
