Bubble Chart

Bubble Chart Size Scaling

Aspose.Slides for Node.js via Java provides support for Bubble chart size scaling. In Aspose.Slides for Node.js via Java ChartSeries.getBubbleSizeScale, ChartSeriesGroup.getBubbleSizeScale and ChartSeriesGroup.setBubbleSizeScale methods have been added. Below sample example is given. 

var pres = new aspose.slides.Presentation();
try {
    var chart = pres.getSlides().get_Item(0).getShapes().addChart(aspose.slides.ChartType.Bubble, 100, 100, 400, 300);
    chart.getChartData().getSeriesGroups().get_Item(0).setBubbleSizeScale(150);
    pres.save("Result.pptx", aspose.slides.SaveFormat.Pptx);
} finally {
    if (pres != null) {
        pres.dispose();
    }
}

Represent Data as Bubble Chart Sizes

Methods setBubbleSizeRepresentation and getBubbleSizeRepresentation have been added to ChartSeries, ChartSeriesGroup classs, 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.

var pres = new aspose.slides.Presentation();
try {
    var chart = pres.getSlides().get_Item(0).getShapes().addChart(aspose.slides.ChartType.Bubble, 50, 50, 600, 400, true);
    chart.getChartData().getSeriesGroups().get_Item(0).setBubbleSizeRepresentation(aspose.slides.BubbleSizeRepresentationType.Width);
    pres.save("Presentation_BubbleSizeRepresentation.pptx", aspose.slides.SaveFormat.Pptx);
} finally {
    if (pres != null) {
        pres.dispose();
    }
}
