%I am getting an empty plot from this code.
x1=linspace(0,500000,1000);
for x=1:17
y=lightint{x,1}
plot(x1,y)
end

It looks like y is a scalar value. Is that intentional?

You're trying to plot a scalar multiple times, which Matlab happily does for you. You won't see anything, because your line style doesn't include a marker for single points. You also forgot hold on, so every iteration will wipe the previous.
x1=linspace(0,500000,1000);
for x=1:17
y=lightint{x,1};
plot(x1,y,'*b')
hold on
end
hold off
