bar chart

Hi powerbiexpert22 

With the core charts, you won't be able to create something similar. To create a point on the bar, you need to use error bars, which don’t work on stacked charts. It might be possible to create something similar with SVG/Deneb. It's worth consulting experts like Kerry Kolosko:
