JFreeChart is easy to extend and can be used in both, the client-side, jfeechart well as the server-side applications. The main core methods in this class are taken from Component, Container, Window, Frame, and Jframe classes. This chapter demonstrates how we can use JFreeChart to create Line Chart from a given set of business data. A 3D effect can be achieved by adding a little extra code, which will take care of creating 3D effect in a pie chart.
ChartFrame class inherits functionalities from parent classes such as Develoepr, Window, Container, and Component classes. Comparable columnKey This method adds or updates a value in the table and sends a DatasetChangeEvent to all registered listeners.

This is a serialized class available in org. Consider we have a file named mobile. This method Returns the plot chart as XYPlot. This chapter demonstrates — how we can use JFreeChart to create Pie Chart from a given set of business data. ChartFactory is an abstract class under the org. David Gilbert is also selling an excellent developer guide on the JFreeChart homepage. String valueAxisLabel, CategoryDataset dataset, PlotOrientation orientation, boolean legend, boolean tooltips, boolean urls The argument java.
This class is immutable, which is a requirement for all RegularTimePeriod subclass. JFreeChart class is the core class under the org. As the name suggests, you can use this dataset to serve XYZ chart. PiePlot3D ; import org. You can use these charts to provide better display and clear information.
Let us keep the above Java code in BarChart. A 3D effect can achieved by adding a little extra code, which will take care of creating 3D effect in a bar chart.
Links and Literature 4. The above method is used in the tutorial example. This makes it convenient to collect series data objects. Following is jrfeechart code to create Time Series Chart from the numbers generated by Math. The client program receives user data and then it uses standard Java and JFreeChart APIs based on requirements to generate the output in the form of either a frame, which can be displayed directly inside the application or independently in the image formats such as JPEG or Dveloper.
String title, PieDataset dataset, boolean legend, boolean tooltips, boolean urls This method creates a pie chart with default guife.
Following is the code to create a Pie Chart by using the above given information. All the methods used for this interface are taken from KeyedValues, Deeveloper, and Dataset interfaces. PiePlot PieDataset dataset It creates a plot that draws a pie chart for the specified dataset. The 3D charts are the ones, which appear in a three-dimensional format. Following is the code to create 3D Pie Chart from the above given information.
String categoryAxisLabel is the label for values placed on X-axis. A chart is a graphical representation of information.

PieDataset ; import org. The following example draws a line chart to show a trend of number of schools opened in different years starting from The package is org. Some of the methods in this class belong to parent classes of this class. Following is the code to create a Bar Chart from the above given information. This method sets the hfreechart used for a series and sends a RendererChangeEvent to all registered listeners. Let us keep the above Java code in PieChart3D.
DefaultPieDataset This constructor creates a new dataset, initially empty. Windows Append the String; C: JfreeChart is an open source library developed in Java. Code Create the following two classes. This chapter explains basic class level and gulde level architectures of JFreeChart to give you an idea about how JFreeChart interacts with different classes and how it fits in your Java based application.
Comparable jfreechrt This method adds a value to the table using comparable keys. This chapter demonstrates how you can use JFreeChart to create Bar Chart from a given set of business data. Some of the methods in this interface are taken from SeriesDateset.
Frame String, JfreeChart chart, boolean scrollpane It constructs a frame. It can be used within Java based applications to create a wide range of charts.
The following code creates 3D Bar Chart from the above given information. In a pie chart, the arc length of each sector is proportional to the quantity that it represents. Consider the following example that depicts various car statistics with the help of a 3D bar chart. There are various tools available, which can be used to create different types of charts.
In such case, displaying the data in the form of charts using JFreeChart programming is very simple. JFreeChart makes it easy for developers to display professional quality charts in their applications.
Y-values can be denoted as null to represent missing values.
