Invisible - Draw graphics using invisible ink?

Description:
This attribute controls the appearance of all graphics produced by Plot methods by determining whether graphics should be visible or invisible.

If the Invisible value of a Plot is non-zero, then all the Plot methods which normally generate graphical output do not do so (you can think of them drawing with "invisible ink"). Such methods do, however, continue to do all the calculations which would be needed to produce the graphics. In particular, the bounding box enclosing the graphics is still calculated and can be retrieved as normal using AST_BOUNDINGBOX. The default value is zero, resulting in all methods drawing graphics as normal, using visible ink.

Type:
Integer (boolean).
Class Applicability:
Plot
All Plots have this attribute.
