I'm new to Google Visualization and haven't seen what I'm looking to do anywhere in the online documentation. I'm displaying a linechart with day/hour on the X axis and 2 graphs - expected and actual on the Y axis. I would like to add a "highlight" graph similar to the red in the image below - when the actual vs expected meets a mathematical formula, I'd like to show a "highlight this data point" as too high (red dot on top) or too low (red dot on bottom)....I only want the red lines / marks to appear when required, ie when the actual vs expected formula indicates "too high" or "too low". If I can't draw the dot at the end of the line, at least drawing a line in another color to indicate an outlier would be useful. Any help would be greatly appreciated.
