Graphing with a Charting Package
Author: Ian Darwin
You need charts or graphs, but don't want to write a lot of code.
Use a charting package.
There are two sets of charting packages that can be used.
The first are "pure Java" or at least "pure Android" packages, written in Java (maybe with GL graphics and/or in C++); these are probably the simplest. An example of this appears in 862 Orientation Changes : From ListView data values to Landscape Charting.
A third, low-budget approach is to use Google Charts in a Webview; only useful if you have guaranteed connectivity and don't mind shipping your raw data up to Google to have them format it into a chart for you.
The following tables summarize first the Java-based packages and secondly the HTML5 packages.
