XChart

XChart is a light weight Java library for plotting data.

Description

XChart is a light-weight and convenient library for plotting data designed to go from data to chart in the least amount of time possible and to take the guess-work out of customizing the chart style.

Usage is very simple: Create a Chart instance, add a series of data to it, and either save it or display it.

Simplest Example

    double[] xData = new double[] { 0.0, 1.0, 2.0 };
    double[] yData = new double[] { 2.0, 1.0, 0.0 };

    // Create Chart
    Chart chart = QuickChart.getChart("Sample Chart", "X", "Y", "y(x)", xData, yData);

    // Show it
    new SwingWrapper(chart).displayChart();

    // Save it
    BitmapEncoder.saveBitmap(chart, "./Sample_Chart", BitmapFormat.PNG);

    // or save it in high-res
    BitmapEncoder.saveBitmapWithDPI(chart, "./Sample_Chart_300_DPI", BitmapFormat.PNG, 300);

Charts can be saved as JPG, PNG, GIF, BMP, EPS, SVG, and PDF.

Chart Customization

All the styling options can be found in one of two possible places: 1) the Chart's StyleManager or 2) the series' set methods. With this chart customization design, all customization options can be quickly "discovered" using an IDE's built in "Content Assist". With centralized styling like this, there is no need to hunt around the entire charting API to find that one customization you're looking for - it's all right in one spot!

Chart Themes

XChart ships with three different themes: Default XChart, GGPlot2 and Matlab. Using a different theme is as simple as setting the Chart's theme with the theme method of the ChartBuilder.

Chart chart = new ChartBuilder().width(800).height(600).theme(ChartTheme.Matlab).build();

Getting Started

Non-Maven

Download Jar: http://knowm.org/open-source/xchart/xchart-change-log

Maven

The XChart release artifacts are hosted on Maven Central.

Add the XChart library as a dependency to your pom.xml file:

    <dependency>
        <groupId>org.knowm.xchart</groupId>
        <artifactId>xchart</artifactId>
        <version>2.6.1</version>
    </dependency>

For snapshots, add the following to your pom.xml file:

    <repository>
      <id>sonatype-oss-snapshot</id>
      <snapshots/>
      <url>https://oss.sonatype.org/content/repositories/snapshots</url>
    </repository>

    <dependency>
      <groupId>org.knowm.xchart</groupId>
      <artifactId>xchart</artifactId>
      <version>2.6.2-SNAPSHOT</version>
    </dependency>

Snapshots can be manually downloaded from Sonatyope: https://oss.sonatype.org/content/groups/public/org/knowm/xchart/xchart/

SBT

To use XChart with the Scala Build Tool (SBT) add the following to your build.sbt

libraryDependencies += "org.knowm.xchart" % "xchart" % "2.6.0" exclude("de.erichseifert.vectorgraphics2d", "VectorGraphics2D") withSources()

(SBT/Ivy does not seem to respect the optional VectorGraphics2D dependency and as it does not exist in Maven Central the build will fail unless it is excluded or available in a local repository.)

Building

mvn clean package
