How do you change the color of legend lines? How do you make x axis go from 0 to 2pi?

plot(rad1, ’red’)
hold on
plot(in, ‘yellow’)
plot(in1, ‘blue’)
plot(in2, ‘green’)
legend({ ‘\theta3(rad)’, ‘r3(in)’, ‘r4(in)’, ‘r5(in)’ })

Would you please write your code down precisely and state detailly about what you wanna do?

- Define the x vector to plot against; the one numeric argument form of plot, as documented, plots against the ordinal position, or
- Set the tick labels as desired independently of the value to the desired values. The first is generally simpler.
legend() will use the linestyle of the lines; you've also not provided a linestyle and so the points may not show up depending upon the actual number in each of the above instructions.

It sounds like you would be well served by going through Ch 9 of MATLAB Onramp. It covers plotting. See the xlim function for specifying axis limits.
