Scatter chart.

Hi Syndicate_Admin ,

You won’t be able to build this chart using a Scatter visual, because the Scatter chart requires a numeric X-axis and doesn’t support a continuous Date axis.

To reproduce the chart you shared (dots over time with a horizontal threshold line), the recommended approach is to use a Line chart with markers enabled and the line hidden. This keeps the Date axis continuous and gives the same visual effect as a scatter plot.

So the Scatter visual isn’t required the Line chart with markers is the supported way to achieve this in Power BI.

FYI:

I’ve attached a sample PBIX file for reference.

Please take a look and let me know if you’d like any adjustments.
