Creating a 3D surface of multiple lines

Hi!

I have two variables (Vf,r) that in my code has generated values of a function (f). Vf is the volume fraction of particles and r is the radius of a particle. My code is designed to run calculations over a specified interval for Vf with a set value of r and then return the values of f. Then, it skips to the next value of r and runs the same calculations a set number of times. In the end I have something that looks like:

r =

   1.0e-04 *

    0.1000    0.2000    0.3000

Vfvec =

    0.0010    0.0010    0.0010
    0.0020    0.0020    0.0020
    0.0030    0.0030    0.0030
    0.0040    0.0040    0.0040
    0.0050    0.0050    0.0050
    0.0060    0.0060    0.0060
    0.0070    0.0070    0.0070
    0.0080    0.0080    0.0080
    0.0090    0.0090    0.0090
    0.0100    0.0100    0.0100

f =

    1.6135    2.2791    2.7901
    1.2143    1.7143    2.0983
    1.0283    1.4512    1.7761
    0.9144    1.2901    1.5786
    0.8352    1.1779    1.4413
    0.7758    1.0939    1.3383
    0.7291    1.0278    1.2573
    0.6910    0.9739    1.1914
    0.6592    0.9289    1.1362
    0.6321    0.8906    1.0892

If I plot all of this in 2D with Vf on the x-axis, I get a plot with three different lines, each corresponding to a certain value of r and with the correct values of f for each line. To make this more presentable, I want to plot this in 3D instead. Basically what I want is to plot the lines side by side instead of on top of each other, preferably but not necessarily creating some kind of 3D surface. How would I do this?

Many thanks in advance.

This works (in R2018a):

figure
surf(r, Vfvec, f)
grid on
xlabel('\bfr\rm')
ylabel('\bfVfvec\rm')
zlabel('\bff\rm')
view(-120, 25)

This uses the data you posted.

This was exactly what I was looking for. Many thanks!
