How do I move a plot in front of another plot, or re-order curves in a plot

If you want to change the order of plots or curves, in order to change their order in the legend or to move one plot or curve in front of another, you must use the Move to Front and Move to Back functions.

If you have multiple curves and/or plots, you will have to click Move to Front on several different curves until you get them into the desired order.
