ince this question was asked a few very nice open source native libraries have been created. These include:

1. ChartDroid
2. AndroidPlot
3. AChartEngine

   And a commercial chart:

   1. ShinobiControls

      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.

      1. rapidandroid (question creator solution)
      2. GraphView
      3. Java Charts for Android

         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.

         The other solutions may present a more straightforward approach.

            ChartDroid is an Intent-based "library application" for static chart and graph generation on Android. It can graph/plot/display numerical data in many representations. As a developer, you need only to have your users install the library, then implement a Content Provider according to this simple specification.

            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?

            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.
