Java: Create a Scatter Chart in PowerPoint

2021-11-02 07:00:36 Written by Koohji

A scatter (XY) chart is a two-dimensional chart that shows the relationship between two sets of variables. Each scatter chart has two axes: a horizontal axis (x-axis) and a vertical axis (y-axis), and it accepts only one data series. In this article, you will learn how to add a scatter chart to a PowerPoint slide using Spire.Presentation for Java.

Install Spire.Presentation for Java

First of all, you're required to add the Spire.Presentation.jar file as a dependency in your Java program. The JAR file can be downloaded from this link. If you use Maven, you can easily import the JAR file in your application by adding the following code to your project's pom.xml file.

Create a Scatter Chart in PowerPoint

Spire.Presentation for Java provides the ShapeCollection.appendChart(ChartType type, Rectangle2D rectangle, boolean init) method to add charts of a certain type to a presentation slide. The ChartType enumeration pre-defines 73 chart types, including scatter chart, column chart, pie chart, etc. The following are the main steps to add a scatter chart in PowerPoint.

Create a Presentation object.
Append a scatter chart to the specific slide using ShapeCollection.appendChart() method.
Set the chart data through ChartData.get().setValue() method.
Set the chart title, axes titles, series labels, etc. using the methods under IChart interface.
Set the grid line style and data point line style.
Save the document to file using Presentation.saveToFile() method.

Add Trendline to Chart in PowerPoint in Java

2019-11-20 03:34:44 Written by Koohji

A trendline is a line superimposed on a chart revealing the overall direction of the data. Spire.Presentation for Java supports adding six different types of trendlines to chart, i.e. linear, logarithmic, polynomial, power, exponential and moving average.

The below example demonstrates how to use Spire.Presentation for Java to add a linear trendline to a chart.

import com.spire.presentation.FileFormat;
import com.spire.presentation.ISlide;
import com.spire.presentation.Presentation;
import com.spire.presentation.charts.IChart;
import com.spire.presentation.charts.ITrendlines;
import com.spire.presentation.charts.TrendlineSimpleType;

public class AddTrendlineToChart {
    public static void main(String[] args) throws Exception {
        //create a Presentation instance
        Presentation ppt = new Presentation();
        //load the PowerPoint document
        ppt.loadFromFile("Chart.pptx");

        //get the first slide
        ISlide slide = ppt.getSlides().get(0);
        //get the chart on the slide
        IChart chart = (IChart)slide.getShapes().get(0);

        //add a linear trendline to the first series of the chart
        ITrendlines trendLine = chart.getSeries().get(0).addTrendLine(TrendlineSimpleType.LINEAR);
        //display equation
        trendLine.setdisplayEquation(true);

        //save the resultant document
        ppt.saveToFile("AddTrendline.pptx", FileFormat.PPTX_2013);
    }
}

Output:

Add Data Labels to Chart in PowerPoint in Java

2019-10-17 09:30:01 Written by Koohji

This article demonstrates how to add data labels to a chart and set the appearance (border style and fill style) for the data labels in PowerPoint using Spire.Presentation for Java. Note some chart types like Surface3D, Surface3DNoColor, Contour and ContourNoColor do not support data labels.

Below screenshot shows the original chart before adding data labels:
