What is the formula to plot a different line style (dots) when the RSI line is above or below the 80/ 20 lines?

Thanks

Here is the formula:

a = rsi(14);
plot(a, "");
b = a < 20 or a > 80;
updatecolor(b, colorTransparent);
plot(a, "", colorRed, ChartLine, StyleDotted);

Thanks for this question and the reply.

I will be using this a lot.

Also, is it possible to color/fill the area just inside the plotted lines but only to the designated levels? (ie. above 80 and below 20 in thee previous example)

Here is an example:

a = rsi(14);
plot(a, "");
b = a < 20 or a > 80;
updatecolor(b, colorTransparent);

b = iff(b > 0, a, 0);
plot(b, "", colorRed|50, ChartLine, StyleDotted|StyleNoScale|StyleWidth0);
plot(a, "", colorRed, ChartLine, StyleDotted);
