Hi all, 

As I was building my scatter plot in power bi, I saw that there is one line appeared in my scatter plot. Can someone tell me why is the line appearing in the scatter plot? Thank you!

What are the fields your put in this scatter chart? Did you set any format of this visual?

it appears to be one of the grid lines - as to why it is darker than the other grid lines I can't say......
