Today, it is the most widely used charting library among Java developers.

A bubble is plotted at the place where x, y coordinate intersect. String title, Plot plot This constructor creates a new chart with the given title and plot.

Some of the methods in this class belong to parent classes of this class. Frame String, JfreeChart chart It constructs a frame. This class provides JFreeChart method to create bar charts, line charts, pie charts, and xy plots including time series data. Comparable key, boolean autoSort, boolean allowDuplicateXValues It constructs a new xy-series that contains no data. ChartFactory is an abstract class under the org.

Exceptions are raised on the occurrence of duplicate or invalid data. There are various tools available, which can be used to create different types of charts. Frame String, JfreeChart chart, boolean scrollpane It constructs a frame. This code helps you to embed a Bubble chart in any AWT based application.

The XY chart scatter is based on one data series consisting of a list of X and Y values.

This method is jfreechart to set the frame size using java. This renderer class is designed for use with the XYPlot class. Category Dataset This type of dataset is used for bar chart, line chart,etc. Here, one value determines the horizontal X position, and the other determines the vertical Y position.

File The source having user input to be used for creating a dataset in the file. Comparable seriesKey, double[ ][ ] data This method adds a series to the collection and sends a DatasetChangeEvent to all registered listeners. This class helps to create AWT Frames. TimeZone zone It constructs a dataset containing a single series more can be addedtied to a specific time zone.

Series Collection Dataset The different categories of series datasets are added to series collection dataset. JfreeChart is an open source library developed in Java. The series dataset is used by XY charts. For enterprise applications, you need to jfreecjart something more robust.

A 3D Bar chart is same as the bar chart additionally with a jfreechhart 3D effect. Comparable key This constructor creates a new empty series. A 3D effect can be achieved by adding a little extra code, which will take care of creating 3D effect in a pie chart. This code helps you to embed a line chart in any AWT based application.

It constructs a new empty series, with the auto-sort flag set as requested, and duplicate values are allowed. You can use these charts to provide better display and clear information. It sets the interior gap and sends a PlotChangeEvent to all registered listeners.

The following example depicts various car statistics with the help jffreechart a bar chart. In such case, displaying the data in the form of charts using JFreeChart programming is very simple. In a pie chart, the arc length of each sector is proportional to the quantity that it represents. All ad methods used for this interface are taken from KeyedValues, Values, and Dataset interfaces.

TimeZone zone It constructs an empty dataset, tied to a specific time zone. The following example draws a line chart to show a trend of number of schools opened in different years starting from The 3D charts are the ones, which appear in a three-dimensional format. Following is the code to create a Bar Chart from the above given information.

Comparable columnKey This method adds a value to the table. This class is a part of org. Database The source having user input to jfrsechart used for creating a dataset in the database. Also, you can do this: This package contains classes and interfaces, which are used for the time related data.

Based on your requirements, you can use any other database.

JFreeChart – Quick Guide

mfreechart Let us keep the above Java code in BarChart3D. This is the default orientation. This is an interface for rendering the format of a single x, y item on a XYPlot.

In this chapter, we will discuss about some of the important packages, classes, and methods from JFreeChart library. The solution was to use a method ChartUtilities. Why not one of the ChartUtilities.
