This article mainly explains the "Java in PPT to create scatter plot what is the implementation method", the article explains the content is simple and clear, easy to learn and understand, the following please follow the editor's ideas slowly in-depth, together to study and learn "Java in PPT to create scatter chart what is the implementation method" it!

Before creating a chart

You need to import the jar package Free Spire.Presentation for Java, which is used to manipulate PPT, in the Java program. You can refer to the following two methods for import:

Method 1: import the jar package manually. You need to download the jar package locally, extract it, and find the jar file in the lib folder. Then follow these steps to import:

Method 2:maven warehouse download and import. You need to configure the maven repository path in the pom.xml file and specify dependencies. The configuration is as follows:

When com.e-iceblue https://repo.e-iceblue.cn/repository/maven-public/ e-iceblue spire.presentation.free 3.9.0 creates a chart

Insert the chart at the specified coordinate location in the slide by specifying the data source. The Jar package provides ShapeCollection.appendChart (ChartType type, Rectangle2D rectangle, boolean init) methods to add specific types of charts to slides, and the ChartType enumeration predefines 73 chart types, including but not limited to scatter charts, column charts, pie charts, and so on.

The creation of a scatter chart is mainly accomplished through the following steps:

Create an instance of the Presentation class.

Use the ShapeCollection.appendChart () method to attach a scatter chart to a specific slide.

Set the chart data through the ChartData.get (). SetValue () method.

Use the method provided by IChart interface to set chart title, axis title, series label, and so on.

Set gridline style and data dotted line style.

Use the Presentation.saveToFile () method to save the document to the specified path.
