The keycolumns settings sets how many columns the legend of a plot should be arranged into. By default, all of the entries in the legends of plots are arranged in a single vertical list. However, for plots with very large number of datasets, it may be preferably to split this list into several columns. The set keycolumns command can be followed by any positive integer, for example:
