I'm using SSDT 12. How would I create a trend line formatted similarly to the one in this thread:

I tried adding a calculated field but it said that aggregated values can't be used and other articles suggest using the 'Plot Chart Area' feature which is no longer present. Any suggestions?
Thanks in advance
