Need help about generating graphs/charts and reports

I am currently working on a system which handles the management by business objectives of an organization.I need to generate reports and also the graphical representation of certain things like employee performance in particular year,company growth etc.So I studied certain tools/APIs for that. Now my question is can I use jasperreports for reporting part of the system and jfreechart for chart/graphical part of system and 开发者_JS百科then integrate it ? or is there any another open source tool/API available for that ? plz help. Thanks in advance...

You can get some idea of the versatility of JFreeChart from the demo and examples. I haven't used JasperReports.

You can use google visualization charts, high charts, jplot.

Google Visualization

High Charts

Jqplot - Uses jquery
