I am super stuck, trying to create a bar/line chart that shows me the number of sales per month.
My modelled data source looks like this:
Now for the "Series" setting of Bar/Line Chart I could do "COUNT(@Order ID)" and it will show me the (total) number of lines = total number of orders (731) in my data source, but only as one datapoint (1) on the X Axis.
I cannot come up with the (probably GROUPBY or something) formula, to actually split the total over the months. I want to aggregate the "@Order Created At" column to months so that it plots the COUNT for each of the months present in column "@Order Created At" as the line chart.
Any help is greatly appreciated 🙏🏻
