In order to retrieve data from firebase database you should check the google docs about it at this site

It clearly says that firebase use asynchronous listeners, so they will automatically get the data when day are modified.

To create charts in android studio I recommend you to use this external implementation from github, by PhilJay . It provides you also all the documentation about the implementation.
