In general, once you actually plot the graphic in a device window, you
would need to re-plot the graphic if you need to alter the dimensional
attributes of the plot.  You can add new objects to an existing plot
quite easily, but within the pre-existing coordinate system or margin
areas. 

Thus, if you need to adjust the x or y axis ranges for example, you
would need to re-draw the graphic.
