title: Android-Charts -- CandleStick Chart
body: <p>Hi i am using <a href="https://github.com/limccn/Android-Charts" rel="nofollow">https://github.com/limccn/Android-Charts</a>  library for showing stock live data on chart in my android app. i am using CandleStick Chart of this library. everything is working fine except one thing is that i am not able to show tool tip when mouse over on any candle stick inside chart for display data. i am using below code for initializing chart. does any one know how to show tool tip or how we can attached any view when user mouse over on any stick of chart.</p>
