Why won't my plot work? (not elementwise issue)

Displaying T and d show this isn't an issue with elementwise operations (which is all I can find searching through the questions). Other plots have worked, so I know its not a graphics card issue, but I'm new to Matlab and can't see what's different from this plot and ones that have worked in the past. This is driving me insane, any help would be greatly appreciated.

lCable = 2;
lPole = 2;
m = 100;
g = 9.81;
w = m*g;
d = linspace(1,1.9,19);
top = w*lCable*lPole;
bottom = d.*sqrt((lPole^2)-(d.^2));
T = top./bottom;
% T = (w*lCable*lPole)./(d.*sqrt((lPole^2)-(d.^2)))
disp(T);
figure()
plot(d,T)
xlim([0 2])
ylim([0 4])
title("Tension of Cable by Distance")
xlabel("distance (Meters)")
ylabel("Tension (Newtons)")
grid on

The T values are around 2000 to 3500 but the ylim was set to [0 4]. I changed the ylim to [0 4000].

I completely missed that! Thank you so much, I was litterally pulling my hair out.
You're welcome!
