Synopsis

x0, y0, x1, y1

Description

Define the positions of the two reference points (x0,y0) and (x1,y1) in the standard coordinate system. The standard coordinate system has its origin in the center of an A4 sheet and uses points (1 pt = 0.353 mm) to measure distances in both dimensions. The x-axis points to the right, and the y-axis points up. The values of these plot parameters are available in INCLAN as intrinsic functions: viewx0, viewy0, viewx1 and viewy1.

Initial values: x0 = -250, y0 = -375, x1 = 250, y1 = 375
