Graphics API

0
Jose Miguel Ordax Cassa (2.4k●4●126●100) | asked Jul 20 '09, 9:45 a.m.
I was thinking to develop my own viewlet where I need to show some
graphics. Is the Graphic API used for reports in Jazz/RTC public and
documented so I can reuse it instead of using third party libraries like
jChart?

Thanks in advance,

Chemi.

Hi Chemi,

There are three Charting APIs within RTC:

(1) Jazz Flash charting engine
=> Client-side technology powered by Flash
=> Used by Work Item Statistics viewlet
=> No API. Strictly internal
=> No documentation

(2) BIRT charting engine
=> Server-side technology powered by Java/Eclipse
=> Used by Reports Web UI and Trend Reports viewlet
=> Public API
=> Documentation:
http://www.eclipse.org/birt/phoenix/

(3) DojoX charting engine
=> Client-side technology powered by JavaScript/CSS/HTML
=> Not used by any component at the moment
=> Public API
=> Documentation:
http://docs.dojocampus.org/dojox/charting/
http://api.dojotoolkit.org/jsdoc/1.3/dojox.charting

I think (3) would be the easiest to learn, the simplest to use and have the most
dynamic capabilities for viewlet requirements.

Thanks,

Mike
