Running Total Multi Line Chart Show Points Not Line
I am trying to create a running total line chart the shows the running total of two events in a series. I can get the information to show, however, one of the "lines" always shows up as data points rather than a line (see the image below). I have the line style set as "plain" and have not changed any of the other default settings. Is there a way for me to create an actual line chart here?
