Sort... Sorting the order of appearance of curves in the key

By default the curve "key" will appear in order of item definition, sorted by ascending label number. However when confronted by a plot with many curves often it is useful to be able to pick out the largest or smallest, and this can be achieved with Sort....

You can sort by any of the criteria X max/min/mag, Y max/min/mag, and the effect will be to reorder the curve key as appropriate.

For example: here is a plot of von Mises Stress for 4624 shells over time - confusion - which is the highest value?

Using Sort... by Y max reorders the key with the top Y values at its top, making it possible to turn on just the top few curves, which are plotted below.
