optionsfeasible=(color=red) - ichki soha rangini o`rnatish;
optionsexcluded=(color=yellow) - tashki ichki soha rangini o`rnatish ;
optionsopen(color=blue, thickness=2) - ochiq chegara chizigi qalinligi va rangini o`rnatish;
Misol:
1. Oshkormas funksiya grafigini chizing (giperbola): .
> with(plots):
>implicitplot(x^2/4-y^2/2=16,x=-20..20,y=-16..16,color=green, thickness=2);
2. Bir rasmga astroida grafigini va astroida grafigi ichiga ellipsni chizing. Astroida va Ellips yozuvi qalin shriftda va Ellips va tenglamasi birgalikda yozilsin. Buning uchun keyingi qatorni tering:
> with(plots):
> eq:=x^2/16+y^2/4=1:
>el:=implicitplot(eq, x=-4..4, y=-2..2, scaling=CONSTRAINED,color=green, thickness=3):
>as:=plot([4*cos(t)^3,2*sin(t)^3,t=0..2*Pi],color=blue, scaling=CONSTRAINED, thickness=2):
> eq1:=convert(eq,string):
> t1:=textplot([1.5,2.5,eq1], font=[TIMES, ITALIC, 10], align=RIGHT):
> t2:=textplot([0.2,2.5,"Ellips:"], font=[TIMES,BOLD,10], align=RIGHT):
> t3:=textplot([1.8,0.4,Astroida], font=[TIMES,BOLD,10], align=LEFT):
> display([as,el,t1,t2,t3]);
3. chiziqlar bilan chegaralangan soha ni quring.
> with(plots):
> inequal({x+y>0, x-y<=1, y=2}, x=-3..3, y=-3..3,optionsfeasible=(color=red),
