Example

The following code snippet adds two bubble series to a presentation chart and configures bubble-specific settings:

C#

using DevExpress.Docs.Office;
using DevExpress.Docs.Presentation;

namespace PresentationApiSample;
public class Program {
    public static async Task Main(string[] _) {

        // Create a presentation and add a blank slide.
        Presentation presentation = new Presentation();
        presentation.Slides.Clear();
        Slide slide = new Slide(SlideLayoutType.Blank);
        presentation.Slides.Add(slide);

        // Insert a chart that fills the slide.
        Chart chart = new Chart();
        chart.Width = presentation.SlideSize.Width;
        chart.Height = presentation.SlideSize.Height;
        slide.Shapes.Add(chart);

        // Configure chart title.
        chart.Title = new ChartTitle(new TextArea("Bubble Chart"));
        chart.TextProperties = new TextProperties { FontSize = 24 };

        // Create the first bubble series.
        BubbleSeries series1 = new BubbleSeries();
        series1.Text = "Series #1";

        // Set argument data (X-axis values).
        series1.Arguments = new ChartNumericData(new double[] { 1, 2, 3, 4, 5 });

        // Set value data (Y-axis values).
        series1.Values = new ChartNumericData(new double[] { 10, 25, 15, 30, 20 });

        // Set bubble size data (determines the size of each bubble).
        series1.BubbleSize = new ChartNumericData(new double[] { 5, 12, 8, 20, 10 });

        // Configure data labels.
        series1.DataLabels.ShowBubbleSize = true;
        series1.DataLabels.LabelPosition = BubbleDataLabelPosition.Center;

        chart.Series.Add(series1);

        // Create the second bubble series.
        BubbleSeries series2 = new BubbleSeries();
        series2.Text = "Series #2";

        // Set argument data (X-axis values).
        series2.Arguments = new ChartNumericData(new double[] { 1, 2, 3, 4, 5 });

        // Set value data (Y-axis values).
        series2.Values = new ChartNumericData(new double[] { 16, 14, 10, 21, 25 });

        // Set bubble size data (determines the size of each bubble).
        series2.BubbleSize = new ChartNumericData(new double[] { 7, 15, 11, 18, 13 });

        // Configure data labels.
        series2.DataLabels.ShowBubbleSize = true;
        series2.DataLabels.LabelPosition = BubbleDataLabelPosition.Center;

        chart.Series.Add(series2);

        // Access the bubble chart view and configure bubble settings.
        BubbleChartView view = (BubbleChartView)chart.Views[0];
        view.BubbleScale = 150;
        view.ShowNegativeBubbles = false;
        view.DisplayBubblesAs3D = true;
        view.SizeRepresentation = BubbleSizeRepresentation.Width;

        // Save the presentation to a file or export it.
        // ...
    }
