Can you show me an example of what you mean.
I’m just not getting the requirement still unfortunately.
‘One separate line for 2018 and one for 2019’?
So do you mean you only want the entire years rolled up into one line. To do that, just change the context to the year in the table.
Also if you want different lines so you can see them on the same chart, then you have two options.
The first is the place the year in the legend of your chart,
Or use CALCULATE and FILTER to only pick up the amounts in a particular year.
CALCULATE( Sales, Year = 2018 )
