ince this question was asked a few very nice open source native libraries have been created. These include:
And a commercial chart:
ORIGINAL
It looks like the creator of this question solved this problem and posted some interesting stuff about it to the Internet. I've linked to his solution along with several others that exist now.
Just to summarize: his solution involved using a JavaScript library (flot) built on top of jQuery. This library was then included in an HTML page which was loaded into a custom WebView. The custom WebView then read data from a custom Java class made accessible to JavaScript code via the WebView.addJavascriptInterface method. Details can be found at the above link.
This is my personal compilation of Android charting and plotting libraries and tools as of March 2012, I might have used some of the previous comments on this page / stackoverflow without referencing, for which I am very thankful.
Due to my low reputation, I cannot post links here, too bad.

It's the only one I've found that is all Java (no webview stuff), is open source, and the author isn't asking for money even if you end up using it in a pay app.

A simple, fast, graphing library for Android featuring scatter plots, line graphs, area plots, histograms, bar charts and heat maps. There is a quick start project in the source, it seems to me that the labels of axes cannot be trivially changed?

Another Java - Android only Library with good looking but limited charts. Obvious choice if you want to quickly embed good looking charts with very little coding effort.

goal was to create graphs in android using any JavaScript or HTML that are stored locally. The app and the graphs should work even if access to Internet is not available.
