5.3.6 The refresh command

The refresh command is rather similar to the replot command, but produces an exact copy of the latest display. This can be useful, for example, after changing the terminal type, to produce a second copy of a multiplot page in a different format. But the crucial difference between this command and replot is that it doesn’t replot anything. Indeed, there could be only textual items and arrows on the present multiplot page, and no graphs to replot.
