Adding list of numbers so it can be used as line graph

Hi Guys,
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.

Hello @bwhite1339

Create a data type that serves this purpose. Every time that field is updated … create an entry that registers this value and that populates your chart.
