Controlling Axes

You can build up various features of a plot bit by bit. For example, you can specify how much of a box to add around the plot with the box function. In fact, you can use any of the following box line options to draw different extents of the box. The sides are number from 1 for the lower side, then clockwise.

"o" gives you all four sides (1:4)
"l" gives you left and lower (2 and 1)
"7" gives you upper and right (3:4)
"c" gives you all except right (1:2, 3)
"u" gives you all except upper (1:2, 4)
"]" gives you all except left (1, 3:4)

The plot function here requests that the axes not be drawn, and the chosen box is then drawn on top of the current plot.
