Hi, I would like some help with plotting a 2D and 3D graph together. I actually have an equation with two varying parameters and I have displayed a 3D plot.What i want is to set a value for the one parameter and plot the line together with the previous surface, so that I can see where this line is placed on the surface.I provide the example to make myself clearer. Itouch50 := -0.4058074876e13*sqrt(1.+h)/(sqrt(ts)*(-500000000.0*ln((625.+125.*h+25.*h^2+5.*h^3)/h)* sqrt(1.+h)+587311661.7)) Itouch := 474335.0379*h*(10300.*2.718281828^(-3.703703704*ts)+1030.*2.718281828^(-3.703703704*ts)* h+490.*2.718281828^(1/(5.*ts+6.))+49.*2.718281828^(1/(5.*ts+6.))*h)/(51200.*sqrt(ln(100.*h))*h+5120.*sqrt(ln(100.*h))*h^2+25600.+12790.*h+511.*h^2) Itouchi := 0.2205799098e13*h*(182.*2.718281828^(-4.081632653*ts)+ 15.*2.718281828^ (2.500000000/ (10.*ts+3.)))/(5000000000.*ln(100.*h)*h+5000000000.+1950427827.*h) p1:=plot3d([ts,Itouch50,h],ts=0..1,h=0.5..1.5,color=green): p3:=plot3d([ts,Itouch,h],ts=0..1,h=0.5..1.5,color=red): p4:=plot3d([ts,Itouchi,h],ts=0..1,h=0.5..1.5,color=yellow): (plots[display])(p1, p3, p4, orientation = [-90, 0], axes = boxed, labels = [Time, Current, Depth]) So what I want is to display the line for each equation of the current against time for h=0.6 on the same surfaces If there is another way to distinguish the line for a particular value of a parameter that could be useful as well. Thanks in advance, Nasos
