How to set up Stochcastic?

 

I have a stockastic set up on my charts with an 80 on the top line and 20 on the bottom line . My problem is that the indicator lines do not show above the 80 line nor do they show below the 20 line.....each are cut off so you see nothing above the 80 or nothing below the 20.

Any help is appreciated

Please see attached chart pic so you can see what I mean.

 

On the common tab of the indicator properties, set max and min
