I want to make a line chart have 3 lines and use date a x-axis. The three lines are: Campaign1, Baseline and real
but the Real line only have 7 days.
I want to have the line chart, 1. 'real' line as a solid line and
2. 'Campaign1','Baseline' as the dashlines
would be nice know how to specify line color for each one--mast item??
3. add a vertical line at 2017-10-07 (which showing before 10-07 is history, after 10-08 are future)
attached the dataset for you info
