Im trying to draw a graph which represents a persons weight(y axis) over time(x axis). I also need to show a marker for an event such as a change in medication on a specific day. Is it possible to add a point to the dataseries with only a time value that gets included in the line drawing but doesnt change the drawing of the line?
A:
Why don't you just add another series for markers and set the points to be x = the marker date, y = 0?

I needed the y value to be on the line not on the bottom of the graph. i ended up getting the two closest dates before and after the marker and working out the y intercept and then adding that as the y value and it shows up exactly where it should
