If you really need chart reports library than I don't think qtjambi has it , I don't know what functionality and complexity you need for charts , It definitely is possible to draw using qtjambi , look at examples . I have no experiences with this , so if you think that what you need is to much to code yourself then look for swt charts library better , as swt is developed and evolving . Another idea is maybe combination of qtjambi + QWebKit for html charts , but this is just speculation :) .
