Hi everyone, I want to draw a well, which actually the function pot[x_]:=Which[x<0,Infinity,0<=x<=a,-v,x>a,0] .. using Plot I am getting a picture which doesn't have the end points connected, I think using `Plot' I can't get the picture I want.
I want it like a well.. i.e; an extra vertical line connecting {a,-v} and {a,0}
In short how can I plot multiple lines in a single figure with Graphics[Line{...}]
