I already did that but that not working. What I meant was is there a way to Mark Size on a Map when Zooming??
Don't use zooming. Just create normal chart and keep value in Size in the marks section.
And then increase the size manually like in above image.
Can you see it..?
Try once with Superstore Data and If it works with Super store data then you'll be able to understand the problem
You can share your workbook with me so that I could take a look.
