A charting software library for Android applications by Dan Dromereschi.

AChartEngine is a charting library for Android applications by Dan Dromereschi. It currently supports the following chart types:

  • line chart
  • interpolated line chart
  • area chart
  • scatter chart
  • time chart
  • bar chart
  • pie chart
  • bubble chart
  • doughnut chart
  • range (high-low) bar chart, including support for gradient colored bars
  • dial chart / gauge

All the above supported chart types can contain multiple series, can be displayed with the X-axis horizontally (default) or vertically and support many other custom features (labeling, colors, zoom & pan, pinch zoom,...). The charts can be built as a view that can be added to a view group or as an intent, such as it can be used to start an activity.

AChartEngine is currently at the 1.1.0 release and is available from the project's web site.
Alternate link A nightly build for version 1.2.0 is available here.

A good way to start is to checkout demo sources and experiment with it. The demo app includes many examples, using almost all AChartEngine features.

A good tutorial can be studied here and another one here.

The AChartEngine Facebook page shows a nice list of applications using it.
