Spider Chart SWT

SWT utility library to generate Spider Chart Diagrams. The library uses all new Java 8 fluent API to generate Spider Diagram.

How To

In OSGi Environment (Eclipse RCP):

Build the library using maven. You will get an OSGi bundle. You just have to install it in your Equinox runtime by just adding it to your RCP target platform.

In Java SE:

Build the library using maven and put the recently built jar file to your application classpath.

Sample Usage

Check out the sample application in the project for the detailed information.

@SpiderChartPlot(name = "iPhone 6", areaColor = DARKORCHID)
public final class IPhone {

	@DataPoints
	public double[] dataPoints() {
		final double[] data = { 4, 3.5, 4, 4.6, 5 };
		return data;
	}

}

@SpiderChartPlot(name = "Nexus 6", areaColor = OLIVE)
public final class Nexus {

	@DataPoints
	public double[] dataPoints() {
		final double[] data = { 4, 3, 3, 4.1, 3 };
		return data;
	}

}

public final class Sample {

	enum Brand {
		COMMUNAL, INTERNATIONAL, LOCAL, OUT_OF_MARKET, STANDARD
	}

	private static SpiderChartViewer viewer;

	private static void buildSpiderChart(final Shell shell) {
		final Supplier<Object> iPhoneData = IPhone::new;
		final Supplier<Object> nexusData = Nexus::new;

		viewer = SpiderChartBuilder.config(shell, settings -> {
			settings.title(title -> title.setText("Smartphone Comparison Scale")).legend(legend -> {
				legend.addItem(iPhoneData);
				legend.addItem(nexusData);
			}).plotter(plotter -> {
				final AxesConfigurer configuration = new AxesConfigurer.Builder().addAxis("Battery", 5, 0)
						.addAxis("Camera", 5, 0).addAxis("Display", 5, 0).addAxis("Memory", 5, 0).addAxis("Brand", 5, 0)
						.build();
				plotter.use(configuration);
			});
		}).viewer(chart -> {
			chart.data(firstData -> firstData.inject(iPhoneData)).data(secondData -> secondData.inject(nexusData));
		});

		// Updating the chart with new parameters
		Display.getDefault().asyncExec(() -> {
			// changing values in runtime
			final LineDataSeq iPhoneDataSequence = LineDataSeq.of(iPhoneData.get(), 2.0, 4.2, 4.1, 42.8, 3.7,
					Brand.INTERNATIONAL);
			// Set the first sequence
			viewer.getChart().getSpiderPlotter().setSeq(0, iPhoneDataSequence);

			// changing axes in runtime
			final AxesConfigurer configuration = new AxesConfigurer.Builder().addAxis("Battery", 5, 0)
					.addAxis("Screen", 5, 0).addAxis("Display", 5, 0).addAxis("Memory", 50, 0).addAxis("Sound", 5, 0)
					.addAxis("Brand", Brand.class).build();

			final LineDataSeq nexusDataSequence = LineDataSeq.of(nexusData.get(), 2.4, 3.2, 2.1, 23.8, 1.7,
					Brand.LOCAL);

			// Set the second sequence
			viewer.getChart().getSpiderPlotter().setSeq(1, nexusDataSequence);
			viewer.getChart().getSpiderPlotter().use(configuration);
			viewer.getChart().getSpiderPlotter().setMarkScalesOnEveryAxis(true);
		});
	}

	public static void main(final String[] args) {
		final Display display = new Display();
		final Shell shell = new Shell(display, SWT.DIALOG_TRIM);
		shell.setSize(800, 750);

		buildSpiderChart(shell);
		shell.open();

		while (!shell.isDisposed()) {
			if (!display.readAndDispatch()) {
				display.sleep();
			}
		}

		viewer.getChart().stopWorker();
		viewer.getChart().dispose();

		display.dispose();
	}
