Non numeric data X plot

I need help to solve this plot:
syms X L
X = 0:L/16:L;
Y = 1 + 2*X;
plot (X,Y);
This is just an example, the function I am trying to solve is a bit complicated.

In this particular case, you can plot something meaningful. In most cases, you cannot plot with unresolved symbolic variables unless you use fplot() or fplot3() or fsurf() to have MATLAB automatically substitute specific numeric values for the unresolved values.
You cannot, for example, plot a family of curves expecting it to show you abstract curves such as "s", "s/2", "s/4", "3s/2" and so on. Plotting always requires that something replaces all symbolic variables with particular numeric values.
syms X L
X = 0:L/16:L;
Y = 1 + 2*X;
fplot3(L, X, Y, [0 20]); xlabel('L'); ylabel('X'); zlabel('Y');

syms X L
X = 0:L/16:L;
for i=1:length(X)
Y(i) = 1 + 2*(X(i)/L);
end
figure
plot(X/L, Y);
xticklabels(string(sym(xticks)) + " L")
