Synoptic Panel Help

Hi there,

I'm trying to do something similar to the image attached with images increasing with percentage, but I can't seem to find out how to do it.

I can see on the templates on Synoptic Designer for Power BI it show's how to do e.g. a shop map where products are sold, but not anything on the % level with images increasing.

Does anybody know how this would work, or could point me to a guide that would be great?

Thanks in advance

Liam
