Is it possible to only plot specific graph in a for loop?

I have a code where i graph a sine wave for every x from 1 to 10, but i only want to graph the sine wave with x=3,7, and 8.

Here's my example code :

---------------------------------------------

t = 0:0.01:2*pi

for x = 1:10

y = sin(x)

plot(t,y)

end

---------------------------------------------

I only want to graph in the same figure when x equals to 3,7,8.

if i use "if", when x is not equal to 3,7,8 , it will erase all the graph recorded.

is it possible?

thankyou

[VBBV]

t = 0:0.01:2*pi
x = [3 7 8];
for k =1:length( [3 7 8])
y(k,:) = sin(t.*x(k));
end
plot(t,y)
legend('x = 3','x =7','x=8')
