How can I sort plot points based on a corresponding vector

I have a huge data file that I need to sort into two groups. The vector is a list of temperatures of a greenhouse, and each value in the vector has a corresponding value in a second vector that has a 1 or 0 next to it (based on whether the vector was open or closed). I want to sort out these two values and plot them separately. How do I get matlab to do this?

idx = logical(OpenClose;
plot(Temperatures(idx), 'b');
hold on
plot(Temperatures(~idx), 'k');
hold off
