Android : Library open source to make Gantt graphics on Android

I use Eclipse with Android api 19. I'm looking for a library to make an app with a Gantt graph of a data series that i receive from a database. I'm searching on Internet but i don't found a lot of answers. I'm looking on Achartengine but it seems that i can't do a Gantt graph with that, and i'm reading about Afreechart (the Android version of Jfreechart, i'm not very sure) but i didn't found an example of that. Can anyone help me? Thanks
