public class BubbleMapChartWidget
extends AbstractChartWidget<BubbleMapChart>
implements IsDatasetCreator<BubbleMapDataset>

BUBBLEMAP chart GWT WIDGET implementation.
A Bubble Map, as known as Proportional Symbol is used to render maps with dots that are scaled according to some numerical value.
It is based on a regular bubble chart where the positioning is done using latitude and longitude to create a legend for the different radi.

extendedChart - new chart

Method Detail

getOptions

public BubbleMapOptions getOptions()

Description copied from interface: IsChart

Returns the options of chart.

Specified by:

getOptions in interface IsChart

Returns:

the options of chart.

newDataset

public BubbleMapDataset newDataset(boolean hidden)

Description copied from interface: IsDatasetCreator

Creates a new dataset related to chart type.

Specified by:

newDataset in interface IsDatasetCreator<BubbleMapDataset>

Parameters:

hidden - if true, it will be initially hidden.

Returns:

a new dataset related to chart type.
