Dynamic graphs,pieCharts,Bars etc

please help..I want开发者_开发问答 to make an android application in which i get values from database and need to show them in graphical,piechart,bars etc format. what is the best way of approach? can i get some sample code of such appliactions..?

There are some great suggestions here: https://stackoverflow.com/questions/424752/any-good-graphing-packages-for-android

Take a look at AChartEngine. It includes a bunch of chart types, a lot of demo code and is free to use for both free or commercial applications.
