How do I add an x and y axis line?

[Anita_T]

This is rather embarrassing but how do you add an X and Y reference line to a bar graph on Power BI?  I need something like this graph or The bubble plot in this story board .   My supervisor is picky and I cannot seem to figure it out.

i have this same question. that one will draw whole lots of lines, what we need is just the center line, not all grids

 You can do this by going into the formatting options (the paint roller icon). Under the Y axis turn gridlines on then you can choose color and width and style.
