| Abstract: | This paper studied a kind of practicalmethod for the automatic implementation of 2D graphs'colletive calculation. Figures which take part in thecolletive calculation can be a part of the graph beingplotted on the screen, and the datas of these figures arepicked up automatically from inside that graph. Thescanning line algorithm has been put forward and wasemploged in searching automatically for the inner andouter contours of the collective calculation of graphs. |
