In this view of the application I need to group the data by date
I think I’m going to go with “down vote”, due to screenshots of textual data, lack of existing code, and general “write my app for me” tone.
How is this screenshot of JSON relevant to the app you posted? I see no connection.
(Posting code as screenshots is impolite and not advised here)
With “date” you mean the “year”?
What should be grouped how? There seem to be names, “GR.X” and a number…
