Paint paint This method sets the paint used for a series and sends a RendererChangeEvent to all registered listeners.
ChartPanel class from the org. String title, PieDataset dataset, boolean legend, boolean tooltips, boolean urls This method creates a 3D pie chart using the specified dataset. String valueAxisLabel, CategoryDataset dataset, PlotOrientation orientation, boolean legend, boolean tooltips, boolean urls This method creates a line chart with 3D effect.
String label The constructor NumberAxis uses default values where necessary.
JAVA – JFreeChart – How To Save a JFreeChart to JPEG File
The series dataset is used by XY charts. A line chart or line graph displays information as a series of data points markers connected by straight line segments. This method creates a bar chart. As the name suggests, you can use this dataset to supply data for pie charts. String title, Plot plot This constructor creates a new chart savd the given title and plot.
Let us keep the above Java code in PieChart3D. Strin range It creates new time series that contains no data. This class represents a sequence of data items in the form of period values, where period is some instance of RegularTimePeriod abstract class such as Time, Day, Hour, Minute, and Second classes.
A 3D Pie chart is same as the pie chart additionally with a nice 3D effect. The solution was to use a method ChartUtilities. Comparable key, double value It sets the data value for a key and sends a DatasetChangeEvent to all registered listeners.
You can generate similar chart for total number of errors occurring in your website at a given interval of time. This package contains classes and interfaces, which are used for the time related data. Comparable columnKey This method adds a value to the table using comparable keys.
Let us keep the above Java code in PieChart. Jdreechart code helps you to embed a pie chart in any AWT based application. String valueAxisLabel, CategoryDataset dataset, PlotOrientation orientation, boolean legend, boolean tooltips, boolean urls. This class is immutable, which is a requirement for all RegularTimePeriod subclass.
The class level architecture explains how various classes from the library interact with each other to create various types of charts. This is a serialized class available in org.
Consider the following example that depicts various car statistics with the help of a 3D bar chart. This method sets the paint used for a series and jfreecnart a RendererChangeEvent to all registered listeners. String valueAxisLabel, CategoryDataset dataset, PlotOrientation orientation, boolean legend, boolean tooltips, boolean urls This method creates a line chart with default settings.
Line Chart shows how data changes at equal time frequency. Hence, this class has the same features as PiePlot class, except it is used to create 3D plots. This chapter explains basic class level and application 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.
Also, you can do this: The functionality should exist as it is possible to do this manually right click menu and PNG option from there. A bar chart uses different orientation horizontal or vertical bars to show comparisons in various categories.
This makes it convenient to collect series data objects. A 3D Bar chart is same as the bar chart additionally savr a nice 3D effect. This is the default orientation. Comparable columnKey This method adds or updates a value in the table and sends a DatasetChangeEvent to all registered listeners.
The package is org. ChartFactory is an abstract class under the org.
This class provides JFreeChart method to create bar charts, line charts, pie charts, and xy plots including time series data. Category Dataset This type of dataset is used for bar chart, line chart,etc.

Series Collection Dataset The different categories of series datasets are added to series collection dataset. Comparable key, boolean autoSort, boolean allowDuplicateXValues It constructs a new xy-series that contains no data.
