How to create a Scatter plot with a single variable?

Hi,

I would like to be able to recreate this graph from tableau in power bi.

The X axis is a measure of correlation for each of the labels on the y-axis. Each individual point in the graph is a date. The points have been changed to bars/lines, but this isn't necessary. The colours represent how strongly the average correlation over the date range is. The line in the middle is created after the fact.

I don't know if this is possible in power bi as you can't create a scatter plot with a single variable, or at least, I can't seem to. Alternatively, I have thought of trying to use some kind of edited bar chart but I think that's even less likely.

Thanks for any help!
