JFreeChart – Quick Guide
This tutorial will guode you understand what exactly JFreeChart is, why is it required, and the various ways to create different types of charts within a Java-based application or independently.
Following is the code to create Line Chart from the information above given. It sets the orientation of Y-axis. But using NumberAxis, class we can set the lower margin and upper margin of domain and range axes. This is a base class for creating the main frame for simple applications.
The class level architecture explains how various classes from the library interact with each other to create various types of charts. 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 PNG.
A 3D Pie chart is same as the pie chart additionally with a developdr 3D effect. It sets the interior gap and sends a PlotChangeEvent to all registered listeners.
This method sets the paint used for a series and sends a RendererChangeEvent to all registered listeners. Following is the code to create an XY Chart from the above given information.
Let us keep the above Java code in PieChart. This chapter demonstrates — how we can use JFreeChart to create Pie Chart from a given set of business data.
It constructs a dataset containing a single series more can be addedtied to the default time zone. A conventional plot has a vertical Y- axis. This method sets the renderer for the primary dataset and sends a change event to all registered listeners. Based on your requirements, you can use any other database.
String title, PieDataset dataset, boolean legend, boolean tooltips, boolean urls This method creates a 3D pie chart using the specified dataset. There are various tools available, which giide be used to create different types of charts. This is the default orientation. These packages, classes, and methods are the most frequently used while creating a variety of charts using JFreeChart library.
For more complex examples have a look at the JFreeChart homepage. By default, the items in the series are sorted into ascending order by x-value, and duplicate x-values are permitted. David Gilbert is also selling jfreecahrt excellent developer guide on the JFreeChart homepage. Category Dataset This type of dataset is used for bar chart, line chart,etc.

Links and Literature 4. This code helps you to embed a Bubble chart in any AWT based application. Second int second, int minute, int hour, int day, int month, int year It creates a new second. ChartFactory is an guice class under the org. As the name suggests, you can use this dataset to jfrechart data for pie charts.
This method Returns the plot chart as XYPlot. Comparable key, boolean autoSort, boolean allowDuplicateXValues It constructs a new xy-series that contains no data. Following is the code to create a Bar Chart from the above given information.
Linux java version “1. This package contains classes and interfaces, which are used for the time related jfreechary. This method is taken from the parent class PiePlot. It provides a collection of utility methods for generating standard charts. A 3D effect can achieved by adding a little extra code, which will take care of creating guids effect in a bar chart.
This chapter demonstrates how you can use JFreeChart to create Bubble Chart from a given set of business data. PiePlot3D class is a subclass of PiePlot class under the same package.

This is an interface through which data develooper the form of x,y,z items can be accessed. This is an interface used as a general purpose dataset, where values are associated with keys.
Let us keep the above Java code in PieChart3D. This is the reason for why we use this class as super class in this tutorial examples. String label The constructor NumberAxis uses default values where necessary.
Locale locale It creates a new second based on the supplied time and tuide zone. The above method is used in the tutorial example. DefaultPieDataset This constructor creates a new dataset, initially empty. Comparable columnKey This method adds a value to the table.
Dimension This method is used to set the frame size using java. This class provides JFreeChart method to create bar charts, line charts, pie charts, and xy plots including time series data.
