Gauge Range Calculations

[HelloCognos]

Hi,
I'm working on a Gauge using Cognos Analytics/Relational Model and the Gauge Range is established based on certain Min/Max and Major Interval values. I have it done but there are two items that I need to perfect.

1) I need to establish the Ranges that needs to be displayed in the Gauge Face based on a division of 5 for each Quarter and based on specific Values and not the ones Cognos Gauge generates based on the above setting.

Is there a way to have constant values for the Gauge that is divided into 5 wedges/sections. I'm using the Notes but the still the Gauge generated values need to match to the #s I'm showing using the Notes.

2) based on the Quarter the user selects, I need use the Conditional Pallet to show only Yellow or other colors between each Wedge of the Five divisions based on the range as the attached sample shows.

Please see my attached. I know it's getting tricky but I'm hoping that I can have one of the above two established.

Thanks in advance for your time.
