Hi, I'm trying to create a variable interval schedule in Excel. I have the data range information plotted in a scatter graph but need to indicate on various points on the already plotted line where a particular event happened. These events also need to be in the legend. It needs to look like this:

Does anyone know how to add those extra marks (on a 45 degree angle) to the already plotted line of data?
I've tried using error bars but they will only show for all points of the line rather than a few selective points.
The only option I have at the moment is to create some lines from the insert shape option and place them on the graph, then insert a text box at the legend. However, I can't seem to group these with the chart, so exporting it into a word document is messy.
Any help would be amazing!
