Control location of the viewport in normalized device coordinates,
where (0.0,0.0) is the bottom left corner and (1.0,1.0) the top right
corner. The default viewport is 0.1 0.1 0.9 0.9, with the first two
numbers giving the location of the bottom left corner and the next
two numbers, the upper right corner. If you use "Viewport" with and
only specify two numbers then PLT centers the viewport about the center
of the plot, thus "View x,y" is the same as "View x,y,1.0-x,1.0-y".
If you do not wish to center the viewport, then you can specify all
four numbers, where the last two numbers refer to the top right corner.
PLT> View .4 .4 ! Viewport extends from (.4,.4) to (.6,.6)
PLT> View .8 .8 .9 .9 ! Use small viewport in top right corner
PLT> View .1 .1 ! Go back to the default viewport
