Abstract
The process concerns the plotting of overextending curves inside a limited display window, with cutting-off of the parts of the curve which extend beyond the imposed display window. The goal is to provide a process for the plotting of overextending curves inside a display window, which optimizes calculation time and plotting time. This goal is achieved by means of a process characterized in that it manages a first process for plotting, applicable to the portions of curves (55) inscribed inside the window, and a second distinct process for processing of the overextending parts (54) of the curve, in that the processing of the overextending parts consists in optimizing travel (51, 52, 53) along the projection of the overextending parts on the window border (X.sub.max, Y.sub.max), and in that the said processing process is entirely executed within the plotting process, and in the course of the plotting of the curve.
