Size Bubbles - Map

[GallopPBI]

Hi All,

I am trying to build a heat map on PBI Desktop.

The location field of the map is calculated column as follows :

Location = 'DB'[Street] & " " & 'DB'[CityName] & " " & 'DB'[Postalcode]

Now on the size bubble I pull in the Postalcode as a count, but the map does not cluster based on the Location field. How can I get over this issue. This works directly if I use the CityName field instead of the calculated column. The problem though is many Postalcodes are outside the map area which is incorrect. So I cannot use the direct column and hence combined the fields in the above.

Please advise.

Thanks

@v-yohua-msft I think the problem is like this...when I select a value from the dropdown and refresh the page link I see the map with multiple bubbles. When I then click the reset green arrow on the dashboard the view becomes fine and shows the clustering. Can you please advise?

Thanks

Hi, @GallopPBI 

Make sure that the categories and fields are correctly categorized in Power BI Desktop. This helps Bing Maps interpret and geocode the data correctly. You can set a data category by selecting a column in the Data view, and then under the Column Tools tab, you can set the Data Category to the appropriate type (for example, Zip Code, City, Address). For more information about data classification, you can check the link:

If possible, add latitude and longitude data to the dataset. This approach eliminates ambiguity in location data, resulting in more accurate mapping. You can then drag these fields into the latitude and longitude buckets in the map visualization settings. This method eliminates the need for Bing to geocode location data, allowing for more accurate clustering and positioning on the map.

If the built-in map visuals in Power BI Desktop don't meet your needs, consider exploring custom visuals from the Power BI Visuals Marketplace, or using Azure Maps visuals for Power BI, which may provide more flexibility and accuracy for specific use cases. Azure Maps visuals allow for detailed customization and potentially more control over how data is displayed and clustered. For more insights on improving map visuals in Power BI, you can review the following documentation:
