enhanced scatter image for points

[Anonymous]

Hi,

I am looking for ways to include images on scatter plot for each bubble. I came across the following link and it seems like this option would work as there are different images assigned per shape within shape column.

However, the video or content doesn't explain how different shapes are assigned or connected with the shape column having values 0 to 10. 0 coresponds to some shape image, but which one and how its is linked.

If someone knows this, can you please explain. I need to put different images per bubble.

Also, please let me know if i need to edit my excel or power bi or both. please be very detailed!

Thank you!
