  I have User home page. I need to show all user accounts points based on bank name in bar chart.

So you have the data: a list of Account that is associated with the user. And for each Account-object you have two attributes:

the Points and the name of the Bank.

That is all you need for a barchart. So where do you get stuck in your attempt to show a barchart?
