Bubble Chart

Bubble Chart Size Scaling

Aspose.Slides for Java provides support for Bubble chart size scaling. In Aspose.Slides for Java IChartSeries.getBubbleSizeScale, IChartSeriesGroup.getBubbleSizeScale and IChartSeriesGroup.setBubbleSizeScale methods have been added. Below sample example is given. 

Presentation pres = new Presentation();
try {
    IChart chart = pres.getSlides().get_Item(0).getShapes().addChart(ChartType.Bubble, 100, 100, 400, 300);

    chart.getChartData().getSeriesGroups().get_Item(0).setBubbleSizeScale(150);

    pres.save("Result.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}

Represent Data as Bubble Chart Sizes

Methods setBubbleSizeRepresentation and getBubbleSizeRepresentation have been added to IChartSeries, IChartSeriesGroup interfaces, and related classes. BubbleSizeRepresentation specifies how the bubble size values are represented in the bubble chart. Possible values are: BubbleSizeRepresentationType.Area and BubbleSizeRepresentationType.Width. Accordingly, BubbleSizeRepresentationType enum has been added to specify the possible ways to represent data as bubble chart sizes. Sample code is given below.

Presentation pres = new Presentation();
try {
    IChart chart = pres.getSlides().get_Item(0).getShapes().addChart(ChartType.Bubble, 50, 50, 600, 400, true);

    chart.getChartData().getSeriesGroups().get_Item(0).setBubbleSizeRepresentation(BubbleSizeRepresentationType.Width);

    pres.save("Presentation_BubbleSizeRepresentation.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}
