[Yongjian Feng]

It is called circular plot. matlab polarplot can do similar thing:

x = linspace(0, 100)
y = x
plot(x, y) % a normal plot
polarplot(x, y) % compare this

the code give like this

But radius is 1(one) and circumferance is 69 so how to change degree to normal num which start from 1 to 69
