AChartEngine is a charting library for Android applications. It currently supports the following chart types:html
- line chart
- area chart
- scatter chart
- time chart
- bar chart
- pie chart
- bubble chart
- doughnut chart
- range (high-low) bar chart
- dial chart / gauge
- combined (any combination of line, cubic line, scatter, bar, range bar, bubble) chart
- cubic line chart
The model and the graphing code is well optimized such as it can handle and display huge number of values.java
AChartEngine is currently at the 1.0.0 release. New chart types will be added in the following releases. Please keep sending your feedback such as we can continually improve this library.android

一、導入jar包
測試
二、直接列出實現的繪圖以及代碼ui
