Please see the attachment. I want to create a plot like the RSI indicator on the top of the picture.
How can i fill some of the data with colors. say, when y > 70 or y < 30 , fill them with read brush.
I have tried fillbetween, the result doesn't fit my need, what can i do?
Do i have to calculate each join point and caculate each individual region to fill?
is there any easy solution?
