Help on gap in between color bar Chart

 

Hi,

I would actually like some expert advice as to why my color bar indicator chart [CZI] (bottom-most chart) always has gaps in between the transition of colors and/or loop onditions. I have attached the coding part below as well. ExtMapBuffer1 is coded with turquoise, ExtMapBuffer7 is coded with dark red, and ExtMapBuffer4 coded with Yellow.

I have tried various methods, but the gap remains. Would appreciate if someone could shed some light on this issue. Thanks

Rgds,

Ken
