    set keycolumns ( <value> | auto )

The setting `keycolumns` sets how many columns the legend of a plot should be arranged into. By default, the legends of plots are arranged into an automatically-selected number of columns, equivalent to the behaviour achieved by issuing the command `set keycolumns auto`. However, if a different arrangement is desired, the `set keycolumns` command can be followed by any positive integer to specify that the legend should be split into that number of columns, as in the example:

    set keycolumns 3
