String title, Plot plot This constructor creates a new chart with the given title and plot. String categoryAxisLabel is the label for values placed on X-axis. Let us keep the above Java code in LineChart.
JFreeChart – Quick Guide
A time series chart displays sequence of data points, which varies at equal intervals of time. PiePlot3D class is a subclass of PiePlot class under the same package. Font titleFont, Plot plot, boolean createLegend. This method adds a series to the collection and sends a DatasetChangeEvent to all registered listeners.
Dimension This method is used to set the frame size using java. Let us keep the above Java code in BarChart.
The following example depicts mobile sale with the help of a pie chart. It sets the lower margin for the axis as a percentage of the axis range and sends an AxisChangeEvent to all registered listeners.
A bubble is plotted at the place where x, y coordinate intersect. Let us keep the jfreecjart Java code in BarChart3D.
This class represents a second in a particular day. This class provides JFreeChart method to create bar charts, line charts, pie charts, and xy plots including time series data. Jfreechxrt is the code to create a Bar Chart from the above given information.

This method is used to set the frame size using java. TimeZone zone It constructs an empty dataset, tied to a specific time zone. This method is taken from javax. JfreeChart Plot plot This constructor creates a new chart based on the supplied plot. The methods, which are taken form the parent classes are used for opening a frame, closing a frame, changing the size, changing the background or foreground color, and listeners.
As the name suggests, you can use this dataset to serve XYZ chart.

A 3D Pie chart savr same as the pie chart additionally with a nice 3D effect. One axis domain axis of the chart shows the specific domain being compared, and the other axis range axis represents discrete values.
Using XYPolt, we can do some utility operations on xy charts. ChartPanel JFreeChart chart, boolean properties, boolean save, boolean print, boolean zoom, boolean tooltips This constructor constructs a JFreeChart panel. It sets the upper margin for the axis as a percentage of the axis range and sends an AxisChangeEvent to all jfreecart listeners.
Following is the code to create Time Series Chart from the numbers generated by Math. The orientation can either be vertical or horizontal.
This method sets the renderer for the primary dataset and sends a change event to all registered listeners. The functionality should exist as it is possible to do this manually right click menu and PNG option from there. As the name suggests, you can use this dataset to serve XY chart.
A conventional plot has a vertical Y- axis. This method sets the paint used for a series and sends a RendererChangeEvent to all registered listeners. This chapter explains how you can read simple data from a database table and then use JFreeChart to create a chart of your choice.
This method Sets the stroke used for a series and sends a RendererChangeEvent to all registered listeners. Let us re-write the above example to generate a JPEG image from a command line. This chapter will explain — how we can read a simple data from a given text file from a given location and then use JFreeChart to create a chart of your choice. Strin range It creates new time series that contains no data. Following is the code to create 3D Pie Chart from the above given information.
String title, PieDataset dataset, boolean legend, boolean tooltips, boolean urls This method creates a pie chart with default settings. Locale locale It creates a new second based on the supplied time and time zone.
It returns JfreeChart type object. This code helps you to embed a Bubble chart in any AWT based application.
Comparable key, double value It sets the data value for a key and sends a DatasetChangeEvent to all registered listeners. Comparable columnKey This method adds or updates a value in the table and sends jtreechart DatasetChangeEvent to all registered listeners. Why not one of the ChartUtilities.
