I'm trying to get a very simple plot by plotting:

  • y=3
  • y=2x
  • x=3

I have no problem to plot y=3 and y=2x

However, how do I plot x=3?


I use this code:

usepackage("amsmath,amssymb"); usepackage("inputenc","utf8"); // code
figure import graph; unitsize(1cm,1cm); xlimits(0,10); ylimits(0,10);
real F(real x) {return 3;}
draw(graph(F,0,10,n=400),linewidth(1pt)+black+solid); real G(real x)
{return 2x;} draw(graph(G,0,10,n=400),linewidth(1pt)+black+solid);
xlimits(0,10,Crop); ylimits(0,10,Crop);

// code supplémentaire
