Hi there I am quite new to MIT App inventor.
I want to create charts/graphs using data stored within TinyDB. Below is my demo display
How could I create something where users could create there unique ID and then the data entered via weeks and weight could save. When a user comes back to the app and does the login the graph shows what they had last time.
This is my current block for creating the chart when entering data into the TinyDB I am just stuck on how to link it too a login system. I am new and not sure where to start. Any help is greatly appreciated!
