Setting the Axes

set xrange [x-range]

Set the default range on the x-axis for all plots. Syntax is the same as in the plot command. Similarly for yrange and zrange. If no range is set, the range is determined from the data, or a standard default is used: [-10:10] for x. To restore the default, use set xrange restore.

set autoscale <option>

Specify that all or part of some range be determined automatically. Options are x, y, xmin, xmax, ymin, ymax, and xy. No option is equivalent to xy. Default setting is xy.

set [no]grid

Draw [don't draw] a grid behind the graph. (Default: no grid.)

set logscale <option>

Specify logarithmic scaling. Options are x, y, and xy. Default is no logarithmic scaling. Typing set logscale with no options is equivalent to set logscale xy.

set polar

Interpret data as polar coordinates. (Default: off, equivalent to set nopolar).)
