TJ's Price Inflation Tracking #2

Open PCalvanelli opened 7 months ago

PCalvanelli commented 7 months ago

Adding temporal trend data would be an interesting addition.

cmoog commented 7 months ago

Completely agree. I plan to add a time series view for each product. Also perhaps a link to download the full history for all products as a raw CSV.

I reckon that TJPI (Trader Joes Price Index) could be a suitable replacement for CPI and PCE. (That's a joke).

Would it be doable to color-code the price change (green for lower new price, red for higher)? It would help for an easy glanceable update.

It would likely be better. CPI as a measurement for price inflation has gone through some unfortunate iterations in the development cycle.

I was going to comment this. If you add a date column, I might actually use data like this for teaching analytics...

Before I get around to adding a decent UI, I'll be updating the full history as a csv data dump here. A download link is included on the home page
