10.5.2 Reordering multiplot items

Items on multiplot canvases are drawn in order of increasing identification number, and thus items with low identification numbers are drawn first, at the back of the multiplot, and items with higher identification numbers are later, towards the front of the multiplot. When new items are added, they are given higher identification numbers than previous items and appear at the front of the multiplot.

If this is not the desired ordering, then the swap command may be used to rearrange items. It takes the identification numbers of two multiplot items and swaps their identification numbers and hence their positions in the ordered sequence. Thus, if, for example, the corner of item 3 disappears behind the corner of item 5, when the converse effect is actually desired, the following command should be issued:

swap 3 5
