Circle Graph Maker - How to Make a Graph in PDF using Java

Circle Graph Maker

This Java API tutorial will teach us how to make a graph in PDF using Java programmatically. You can generate multiple types of graphs using this enterprise-level library. However, in this guide, we will write steps and the code snippet to build a circle graph maker in a Java application. Once you are done with the code snippet, you can automate the graph creation easily. In addition, we will explore some advanced methods exposed by the API we will use in this article.

We will cover the following topics:

Circle Graph Maker - API installation

We are going to use this power PDF API for Java. There is a wide range of methods available to meet your business requirements. In fact, you can either download the API or install it using the following Maven configurations.

How to make a Graph in PDF using Java

You may follow the steps and the code snippets mentioned below:

  1. Create an object of the Document class.
  2. Invoke the getPages().add() method to add a page to pages collection of PDF file.
  3. Initializes a new instance of the Graph class with certain dimensions.
  4. Initialize a new instance of the BorderInfo class.
  5. Invoke the setBorder method to set the border of the graph.
  6. Create an instance of the Circle class and specify the parameters.
  7. Now, call the getGraphInfo().setColor method to set the graph color.
  8. Add Graph object to paragraphs collection of page by calling the getParagraphs().add(graph) method.
  9. Invoke the save method to save the PDF file.

Copy & paste the following code into your main file:

// Create an object of the Document class
Document pdfDocument = new Document();
// Invoke the getPages().add() method to add page to pages collection of PDF file
Page page = pdfDocument.getPages().add();
// Initializes a new instance of the Graph class with certain dimensions
Graph graph = new Graph(400, 200);
// Initialize a new instance of the BorderInfo class
BorderInfo borderInfo = new BorderInfo(BorderSide.All, Color.getGreen());
// Invoke the setBorder method to set the border of the graph
graph.setBorder(borderInfo);
// Create an instance of the Circle class and specify the parameters
Circle circle = new Circle(100,100,40);
// Now, call the getGraphInfo().setColor method to set the graph color
circle.getGraphInfo().setColor(Color.getGreenYellow());
graph.getShapes().add(circle);
// Add Graph object to paragraphs collection of page by calling the getParagraphs().add(graph) method
page.getParagraphs().add(graph);
// Invoke the save method to save the PDF file
pdfDocument.save( "DrawingCircle1_out.pdf");

Generate a filled Circle graph

The following code snippet is to generate a filled circle graph programmatically:

Copy & paste the following code into your main file:

// Create an object of the Document class
Document pdfDocument = new Document();
// Invoke the getPages().add() method to add page to pages collection of PDF file
Page page = pdfDocument.getPages().add();
// Initializes a new instance of the Graph class with certain dimensions
Graph graph = new Graph(400, 200);
// Initialize a new instance of the BorderInfo class
BorderInfo borderInfo = new BorderInfo(BorderSide.All, Color.getGreen());
// Invoke the setBorder method to set the border of the graph
graph.setBorder(borderInfo);
// Create an instance of the Circle class and specify the parameters
Circle circle = new Circle(100,100,40);
// Now, call the getGraphInfo().setColor method to set the graph color
circle.getGraphInfo().setColor(Color.getGreenYellow());
// Invoke the setFillColor method to sets a Color object that indicates the fill color of the graph. https://reference.aspose.com/pdf/java/com.aspose.pdf/GraphInfo#setFillColor-com.aspose.pdf.Color-
circle.getGraphInfo().setFillColor(Color.getGreenYellow());
graph.getShapes().add(circle);
// Add Graph object to paragraphs collection of page by calling the getParagraphs().add(graph) method
page.getParagraphs().add(graph);
// Invoke the save method to save the PDF file
pdfDocument.save( "DrawingCircle1_out.pdf");
