Setting the ranges for Two-dimensional plots

Note that gnuplot automatically sets the range for the x and y variables. you can specify ranges for none, either or both the x and y axes. For example, you can tell gnuplot to plot exactly two cycles of the sine wave by setting the x range to go from -2 pi to 2 pi, which is represented below as [ -2 * pi : 2 * pi ]. The command looks like this:
plot [-2 * pi : 2 * pi] sin(x)By specifying two ranges, you can also control the y range as well. This example shows the plot's y-axis going from -1.5 to 1.5:
plot [-2 * pi : 2 * pi] [-1.5:1.5] sin(x)These ranges can also be set using the set xrange and set yrange commands.
