![XYZ].Margin
Corresponding Plot Keyword: [XYZ]Margin A two-element array specifying the margin around the sides of the plot window, in units of character size. Default margins are 10 (left margin) and 3 (right margin) for the x-axis, 4 (bottom margin) and 2 (top margin) for the y-axis. For the z-axis the default margins are both 0.
When calculating the size and position of the plot window, PV-WAVE first determines the plot region, the area enclosing the window plus the axis annotation and titles. It then subtracts the appropriate margin from each side, obtaining the window.
