Firstly, thanks for reading.
I wish to add a vertical line mathematically (without drawing it in) to the following chart.
The line I want to add is basically x = 40 (I've drawn it here).
I have trouble doing this because when I go to add series, the data it tries to plot it against is the x-axis.
Any ideas?
Thanks again.
