Data Bars in a Table

Hi LuisNC ，

When you set the conditional formatting with data bars, you can only set the maximum and minimum values, you can't set them as percentages. So we need to create a percentage column and then set the conditional formatting for it. I created a sample pbix file(see the attachment), please check if that is what you want.

1. Create a measure as below to get the percent of per customer 

Percent = 
VAR _allamount =
    CALCULATE ( SUM ( 'Table'[Amount] ), ALL ( 'Table' ) )
RETURN
    DIVIDE ( SUM ( 'Table'[Amount] ), _allamount )

2. Add the new measure on the visual and configure conditional formatting for it as below screenshot

If the above one can't help you, please provide some raw data in your tables(exclude sensitive data) with Text format and your expected result with backend logic and special examples. It would be helpful to find out the solution. You can refer the following link to share the required info:

And It is better if you can share a simplified pbix file. You can refer the following link to upload the file to the community. Thank you.
