void acrop(mode) SVC.C Level 2
int mode = 0 to crop lines at the edge of the plot region as defined by the call to area2d() (default).
= 1 to turn off the line cropping.
The GraphiC default is to crop the lines at the edges of the plot region (i.e., the rectangle defined by the axes). To turn off this feature call acrop(1). This call automatically moves the cropping to the edge of the drawing page. The cropping is automatically reset to the default value after each call to curve drawing routines.
