3D Plotting Help Linear Eq. w/ Changing Var in Z

Dear people,

Right here I have a 2D graph of a very simple linear equation. After experimenting for hours with surf/plot3 I would love to get some help with the following goal.

2D graph: VAR1 = 5:.1:15;

C1 = 5; VAR2 = 0.4; g = 1/9.80665;

R = VAR2*VAR1*g*200*.85*3.6;

f1 = (((R*1000)/C1)/(3600));

plot(f1,R) grid on; pbaspect([1 2 3]) ylim([100 450]); xlim([0 15]); xticks([0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15])

My goal is to plot this linear eq. a multiple times in a third axis, with variables changing. I would like to have C1 change from 5 to 25 and VAR2 from 0.15 to 0.85 at the same time. So every time the linear equation with a different value for C1 and VAR2 is plotted behind the other, I expect to see a twisted and shifted plane.

How to do this? My experience with 3D graphs is too small to wrap my head around the syntaxes and logic in order to code this. I tried to make a vector e.g. 0.15:0.007:0.85 and plug it in everywhere using plot3(x,y,z) but nothing works. It turns out to be a set of lines going in the third direction, opposed to what I would like to see, a set of linear equations shifting and changing slope after each other in a third axis.

like this: VAR1 = 5:.1:15; VAR2 = transpose(0.15:0.007:0.85); g = 1/9.80665; C1 = 5;

R = VAR2*VAR1*g*200*.85*3.6; f1 = (((R*1000)/C1)/(3600)); plot3(f1,VAR2,R) grid on;

Hopefully somebody could help me out in any way here!

Try running it in a loop and using 'hold on' so the plots all come out in one figure.

i.e. for z=1:20

    figure
    hold on
    plot3(x,y,z)
end

Thanks for your reply! I don't know how to combine the for loop function in such a way it plots a linear eq. in the 3th dimension..
