I simply want to add an xline with
a specified position, a specified color, a specified linewidth, a label and a specified label position.
I have tried every pertubation of what I think is possible, but it never works. Best I can achieve is a line with a specified color and a label on the left side. As soon as I try to add a linewidth it only returns invalid parameter/value pair.
It would be very helfpful if somebody could tell me how this is supposed to work.
