I am working on an assessment tracker, and I need a way to connect two points that have a null value between them.
Students have a screener (point 1), and based on the results of the screener, they will be supported and assessed in one area of the screener (green line, point 2), then they will have the whole screener again (point 3).
Unfortunately, since they aren't assessed on each point at Point 2, I just have dots for point 1 and 3. I need them all to be lines to show overall growth/change, and I can't find a way to "plot null values".
