Android Question Creating a curve graph

[iamfanghan]

Hi there is it possible to create such a graph using GoogleChart? If it is, can anyone guide me on the codings? I could do for trendline in scatter but not for curve line.. Need help desperately.

Have a look at my GraphView library, you can make a graph like that with Dates!

I did but couldn't figure out how to do so. I manage to make a trendline using scatter chart which gets me a quadratic line. My lack of knowledge is drowning me

There is an example i made on the link i provided you with, take a look at it, it is easy to use!

Looks simple enough to do without any library, just a canvas.
