Corresponding Plot Keyword: None.

Contains a six-element vector. The first four elements specify in device coordinates a rectangle used to clip the graphics window. The rectangle is specified in the form [(x0, y0), (x1 , y1)]. The coordinates specify the lower-left and upper-right corners of the clipping rectangle, respectively. Normally the clipping rectangle is set to the Data Plot Area (the area bounded by the coordinate axes). The last two elements of this system variable are reserved for internal use by PV‑WAVE.
