I would like to have different colors for different range of utilization ratios in the model to visually inspect. How to set the rages and different color?
This can be achieved using the options available under diagrams> design results. Please refer snap below with steps.
Using the above steps you can set the limits as well as color as per your choice. Here, as shown in my attached file in step number 3, you need to select detailed diagram under "color" option. Once you select the detailed diagram the table will expand and the "TO" column will be editable. Now, just under the "Detailed Diagram" option, there is a field for "No. of bands". As per the step 4 in my attached file, you can change the value as per your need. May be you can use 3 , if you need 3 bands. Now, as per step 5 you can put your own range and also the colors can be changed just by double clicking on them.
