I am trying to create an app that allows a person to track the value of their bank account over time.
The trouble I am having is in modifying a thing/adding a new thing. For example if the user enters today “Bank Account 1” has $1000 in it and then tomorrow enters $500, I need to be able to keep both numbers to show on a graph.
I am sure there is a simple solution for this but I cannot work it out.
Any help would be greatly appreciated.
