My project for this year's Google Sommer of Code will be to contribute new chart types for the BIRT project.

Personal Details

Name: Karsten Knese

E-mail: Karsten.Knese@web.de

Skype: kook1987

Mentor: Ahti Kitsik

Full proposal: Proposal

Abstract

As there were some request about new chart types for BIRT the goal of my project is to add three new chart types.

  • donut chart
  • venn diagram
  • radar diagram

Description

BIRT already provides several chart types for designing customs reports. I found some open bugs and help-wanted entries in bugzilla.

Donut chart

This chart will be implemented based on the existing pie chart.

Radar diagram

This chart shows data information grouped by categories.

Venn diagram

This chart shows similarities and differences of several datasets.

Project plan

Here you can find the timeline for this project including all milestones.

Milestone Date Description
M1 June 07 Getting organizational things done like SVN repository etc.
M2 June 10 Creating base frame for all three chart types.
Interface and associated implementation class
M3 June 14 Clear which classes of the existing BIRT source have to be patched
M4 July 5 Implementing donut chart based on the existing pie chart
M5 July 13 Testing donut chart - 'Pencil down' for midterm evaluation
M6 July 26 Implementing radar chart
M7 August 10 Implementing venn diagram
Pencil down August 17 Integrating source into BIRT source, do final documentation

Availuable Features

M1
SVN Repository
Source code is hosted at google code for eclipse foundation project. Later it will be integrated in BIRT.

Here you can find the repository and additional information.


M2
Base frame
Source contains interfaces and implementation classes for the base series definition of all three types.

TODO: Check howto write plugin in a way, it is totally independent and can be connected with extension points.

new chart types Set of the chart type classes.
M3
Rendering classes
This is a list of classes which has to be implemented. Cause the first chart - donut chart - is based on the existing pie chart, the list shows the existing classes of the pie chart.
  • org.eclipse.birt.chart.ui.swt.series.PieSeriesUIProvider
  • org.eclipse.birt.chart.ui.swt.type
  • org.eclipse.birt.chart.ui.swt.wizard.format.popup.series.PieTitleSheet
  • org.eclipse.birt.chart.ui.swt.series
  • org.eclipse.birt.chart.render.Pie
  • org.eclipse.birt.chart.render.

M3
Donut Chart
A few screenshots of the implemented donut chart. Functions are the same as the already existing Pie chart.
Donut chart compilation Donut Compilation



M3
Venn diagram
A few screenshots of the implemented venn diagram <br\>

There are a few restrictions:

  • restricted to three datasets
  • datasets have to be lists of datatypes

There are a few featues:

  • Intersection color will be generated of additive or subtractive colormixing.
  • Intersection areas in charts with three datasets that aren't real will be colored in a transparent way.

Comments, suggestions, ideas

I'm proud to take part in GSoC 2009. As it is my first project I'm happy about every help.
So feel free writing every comments you have. :)
