Power BI Heat Map Question to group more data

Good morning! 

Yes and Thank you for your response.

In the ideal world, I would like to see it broken out in the following way but not totally sure what would be beat. Grouped in zip codes by amount (heat map?) of wealth capacity groups. For example Group A would be @500 - $2500 to $4999 Group B  $5000 - 9999 and so on. But I am not clear it it should be done that way or grouped by indivual ID's and then values are the wealth capacities?

In the attached photo is where I am at, in the value on the top of the screen for postal codes it shows 161 to 1.6K. I would imagine that should be wealth capacities? Not sure. 

Another question is sometimes it tells me error, too many zip codes to display. They are zips repeated, how would you account for that?

My ideal thought is for the map to look like this where the darker would be the highest wealth capacity that we could see by city.
