Other ideas

Project team member and potential mentors, add your content here. The format suggested below is just an idea. Play with the layout, but please don't mess with content provided by other projects. Please be sure to follow branding guidelines (e.g. "Eclipse Dash", not "Dash"). Putting things in alphabetical order seems like a fair thing to do. Links to content hosted elsewhere are fine, but bear in mind that this page will likely be the main point of contact for people who are not already inside your community.

Eclipse SWTChart

SWTChart is a powerful library to create charts and display data using SWT. So, it can be easily used in Java desktop applications. Only a few lines of code are necessary to create interactive and feature rich charts:

public class MyChart extends MassSpectrumChart {

  public MyChart(Composite parent) {
    super(parent, SWT.NONE);
    initialize();
  }

  private void initialize() {

    IChartSettings chartSettings = getChartSettings();
    chartSettings.setCreateMenu(true);
    applySettings(chartSettings);
    //
    List<IBarSeriesData> barSeriesDataList = new ArrayList<IBarSeriesData>();
    IBarSeriesData barSeriesData = new BarSeriesData(SeriesConverter.getSeriesXY(SeriesConverter.BAR_SERIES_1));
    barSeriesDataList.add(barSeriesData);
    //
    addSeriesData(barSeriesDataList);
  }
}

The source code is located here and can easily be cloned: https://github.com/eclipse/swtchart/

If you are interested in one of the topics you have to apply on the mailing list.

Topic 1: Extending the export options

Many export options are contained already, e.g. to bitmaps as well as to scripts. The R script option is really helpful, especially when preparing scientific charts for publication. As the data is stored in a generic way, many different export options can be implemented. The task of topic 1 would be to add/extend the options: *.svg, *.eps, *.pdf and to put a pre-configured LaTeX table into the clipboard.

Topic 2: Handling large data sets

SWTChart already contains a function to compress the data and reduce the time to plot the series. Compressing large data sets could be improved, e.g. to lazily load just the data that is needed, depending on the resolution of the screen. Even when handling large datasets, details should be displayed when zooming in.

Topic 3: Default charts

This topic contains to add default charts, which could be easily re-used, e.g. a PCA chart or others.
