JFreeChart tutorial – learn how to create charts in Java

A line chart is a basic type of chart which displays information as a series of data points connected by straight line segments. A time series chart displays sequence of data points, which varies at equal intervals of time. JFreeChart is easy to extend and can be used in both, the client-side, as well as the server-side applications.

With Orson Charts 1. You can use these charts to provide better display and clear information.

It contains utility classes used for creating frames for pre-configured charts. Here is an example: This tutorial will help 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. For the last couple of days, my Galaxy Nexus S has been going to sleep and not waking up again restarting required either removing the battery, or plugging in and removing the charger, which is not so convenient.

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.


If the Library specifies a version number of this License which applies to it and “any later version”, you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. TimeSeries calculates range incorrectly in addOrUpdate ; Pie Chart Demo 1″ ; demo.

SVG not supported in your browser! Rendering anomaly for XYPlots; In Orson Charts, we’ve defined the CategoryDataset3D interface as the source for data, and jfrechart an easy-to-use implementation StandardCategoryDataset3D people that have used JFreeChartanother chart library I developed, will find this approach very familiar.

JFreeChart –

Some of the methods in this interface are taken from SeriesDateset interface. It sets the alpha-transparency for the plot and sends a PlotChangeEvent to all registered listeners. In the pie chart below, the percentage for each data item is shown in the legend: TimeSeries calculates range incorrectly in addOrUpdate ; This interface extends Guife and DataSet interfaces.

CategoryPointerAnnotation line calculation; The first step in creating this chart is to get the data in a form that can be used to create a bar chart in fact, a stacked bar chart in this case.

JFreeChart – Quick Guide

And names are important. Java doesn’t have much client-side presence in the browser anymore, nor has it made much ground on mobile devices. Compare the axis and grid lines in the following two charts based on one of the JFreeChart demos. Here’s the link if you want to try the demo: JFreeChart was started by David Gilbert in The wok capacity can be treated as number of hours that is plotted as bubbles in the chart. This is a general class available in org.


DateAxis endless loop by Martin Hoeller ; String title, Plot plot This constructor creates a new chart with the given title and plot. In our case the renderer is a StackedBarRenderer3Dso we get a reference to this and again apply the necessary cast. Database The source having user input to be used for creating a dataset in the database. It’s just intended to be indicative. Stroke stroke This method Sets the stroke used for a series and sends a RendererChangeEvent to all registered listeners.


It is their country, and their vote, I won’t argue with that. Over the coming weeks, 1.015 aim to post a few entries highlighting some of the new features in JFreeChart 1. Following is the code to create Bubble Chart from the above given information. The generators also have access to jfredchart full dataset at the point that labels are created, so a custom generator can compute any data metric min, max, mean etc for inclusion in labels. Next, I make the chart-box the walls of the 3D plot transparent so that the background image is not completely obscured by the chartto do this, just specify a color with an alpha-value of less than Here is a sample chart created by JFreeChart: The complete source for the demo is here there’s very little code in addition to what I’ve already shown you.

And have a good guid A bubble chart displays information in three-dimensional way.
