Open source frameworksto generate graphical reports?

Can any one suggest me any o开发者_如何学Cpen source framework to generate reports in android apps? (Some thing like 'Core-plot' for iPhone development)

iText is available for android, although I don't know how stable it is:

There are several chart libraries for android:

And Femi just posted a link to a related question, so I will stop here.

See https://stackoverflow.com/questions/424752/any-good-graphing-packages-for-android for an existing discussion.

Take a look at AChartEngine. It includes a bunch of chart types, a lot of demo code and is free to use for both free or commercial applications.
