我是pine-script的新手，想寻求帮助
我已经尝试了好几天了，我知道答案将是如此简单...
我希望make脚本可以在make方程后绘制3条线的水平线
p1 = can be change this number in option script
r1 = can be change this number in option script
z= can be change this number in option script
p2= p1*z
r2= r1*z
x1 = (r2^2+p2^2)/0.5
if 5 > x1 <=3
plot(x1, color=red)
or
18 > x1 <= 9
plot(x1, color=yellow)
or
80 > x1 <= 20
plot(x1, color=green)
希望所有图都是实线的水平线
