So the component/code should draw something like this (where 'Under revision' would be the active status for this quote): Example chart

I wondered how they are generated and if they are generated everytime I open the app or are stored (cached). It's just a canvas (programmatically) or they use XML? Something like this, and then programmatically they add the letter: <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle"> <size android:width="1px" android:height="1dp"/> <solid android:color="#FFFFF5EE/> </shape> adneal are generated everytime I open the app or are stored (cached) Little column A, little column B.
