I’m trying to build a chart that displays the total value of items sold each day.
I’m retrieving the data from a “sales” database, that has the following fields:
On the X axis the date, so each database entry has it’s date so there are multiple entries with the same date, so i want to show the date grouped by Sold_date, interval 1 day.
and on the Y axis the total value sold per day,
So i was thinking of something along the lines of:
list 1: each item’s Quantity grouped by sold_date
list 2: each item’s sold_price grouped by sold_date
the issue is it seems that that doesn’t work as it doesn’t propose me to group it by date.
Does anyone know how i’m supposed to do this ??
