I wanna use Power Bi Rain Bow Gauge. but I have difficulty in choosing the parameter. I need to know the concept of the gauge and the type of the parameters it gives. for example i want to show the rate of damage over the total sell.
You can use TachoMeter for your purpose. Add this visual from AppSource to your Power BI Desktop. Now follow these below steps to achieve your required output-

ratio = SUM(your_table_name[damage])/SUM(your_table_name[sell])
Step-2: Create these below 4 measure to set different point in the TachoMeter-
1. point_1 = 0
2. point_2 = 0.5
3. point_3 = 0.75
4. point_4 = 1
Now configure your TachoMeter as shown in the below image. You can also see your final output in the image-
