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

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 | Inline 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
SVN Repository |
M1 | 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. |
Which classes have to be created? |
M2 | If you have a look at source located like it is in M1 descripted, you see that now that are an interface and an implementation class. |

new chart types |
As there are almost every classes are located, there will be an information left how to create a new plugin, extending existing BIRT code without patching any line of code. For example, the PIE chart will be rendered in die generator.render-phase. This is a hard coded piece of BIRT. But the question will be how to insert new chart types.
Next steps
Next step will be to locate all required classes. Therefore you can decide how to create a new chart type.
List every class which has to be implemented. Clear how to combine new chart types with extension points of existing BIRT Framework.
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. :)
