It seems that there is a bug with the bar color:
- if value is positive even the root bar take the color for set for positive (blue)
- while it remains lighr gray for negatives values (it should turn to purple)
It seems that the same behaiviour occours even using the conditional formatting instead of data bars setting available in the format.
Any idea?
Please check the picture attached which explains better the scenario. I can even share the sample .pbix (I understand that here is not directly possible).
Hi, @acitsme
According to your description, I can not clearly understand your problem scenario.
If you think that it’s a bug that existed in Power BI. You can go to the Issue forum of Power BI to submit a new issue and explain your scenario step by step. Then members of our team will test based on your scenario and submit it to Microsoft if it does exist.

I found the cause of my problem with decomposition tree.
If the value of the measure you set into analyze is negative than it is not showed when the data bars Start is left to "Auto".
This is definetively a bug. Can anyone rise this to Microsoft?
