How to graph 'trapz' function

I am using a trapz function to estimate the area under a function, and am getting the answer, but I was wondering if there was any way to graph the trapeziums that the function is using to calculate the area, rather than just getting an answer down the bottom.
Side note: does anyone know why my ylim is giving an error of "Array indices must be positive integers or logical values"?
Thanks!
x=0:0.1:6;
y=(30-(exp(-2.3*x)*30))/(0.6*57400)*100-(0.015*x)
plot(x,y)
ylim ([0 0.07])
Q = trapz(x,y)
