A journal instructs authors that curves in a graph should not cross text labels. This creates a dilemma of how to put a label where there are many curves. One possibility is to put a "white out" where you want to add a label, after you have plotted the curves and before inserting the label.
But I think there is no sense of time order of "first" and "second" item on a graph. So I am wondering if there is another solution.
( Currently I terminate the plots in the vicinity of the lable and then restart them after the label. Obviously a slow process. )
