Not seeing second plot data

I'm plotting sin(theta) and theta, and that's working. But I'm also trying to plot the error between the two as a percentage, and plot that against theta. The second plot shows up, but there's no data. Please let me know if you can reproduce, and if I'm doing something wrong.
Also, how can I print out the values of the pct series so I can see the actual numbers?
Thanks.
theta = 0:0.02:1;
y = sin(theta);
plot(theta, y, theta, theta)
grid
pct = 100 - (100 * (theta - y) / y);
plot(theta, pct)
grid

%if true
theta = 0:0.02:1;
y = sin(theta);
figure(1)
plot(theta, y, theta, theta)
grid
pct = 100 - (100 * (theta - y)./ y);
figure(2)
plot(theta, pct)
grid
Try this For second figure, use element wise division operator

theta = 0:0.02:1;
y = sin(theta);
plot(theta, y, theta, 1- (theta - y)./y);%need ./ also to keep it the same scale chose 1 instead of 100
