Can anyone recommend a library open-source for android that supports real-time rendering? I need to make a ECG line chart.

I Googled and all I found are library with fee like graphwidget or aichart..

There's AChartEngine and GraphView. You may also want to search for Java charting and not specifically Android charting.
