Margins¶

The margins around the plot and text elements are controlled by the plot_margin parameter in theme() and the margin parameter in element_text() respectively.

Now the parameters plot_margin and margin accept a number or a list of numbers.

A number or list of one number is specified: the same margin it applied to all four sides.
A list of two numbers: the first margin applies to the top and bottom, the second - to the left and right.
A list of three numbers: the first margin applies to the top, the second - to the right and left, the third - to the bottom.
A list of four numbers: the margins are applied to the top, right, bottom and left in that order.

It is acceptable to use None for any side; in this case, the default side value for this element will be used.
