Filled maps are a popular visualization type in Power BI, enabling you to display data on geographic regions using color gradients.

However, there are times when you may encounter the frustrating issue of a blank filled map.

In this blog post, I'll explore common reasons why a filled map in Power BI might appear blank and provide solutions to resolve this issue.

1. Data Mismatch: The most common reason for a blank filled map is a mismatch between the data in your dataset and the geographic data recognized by Power BI. This occurs when Power BI can't match the data you have to the appropriate geographic regions.

   • Solution: Double-check the names of your geographic data in your dataset and make sure they match the names recognized by Power BI. Ensure that you're using recognized geographical columns like "Country," "State," or "City."

2. Geocoding Issues: Geocoding is the process of converting location names (e.g., city, state) into geographic coordinates (latitude and longitude). If there are issues with geocoding, it can lead to a blank filled map.

   • Solution: Verify that your data is correctly geocoded. You can use Power BI's built-in geocoding capabilities or a custom geocoding service to ensure accurate coordinates for your locations.

3. Missing or Incorrect Data: Sometimes, the issue may be due to missing or incorrect data. If your dataset lacks essential geographic data or if there are errors in the data, it can result in a blank map.

   • Solution: Review your dataset for missing or incorrect geographic data. Ensure that all relevant data is present and accurate.

4. Map Zoom Level: The filled map in Power BI may sometimes appear blank when the map's zoom level is not set correctly. If you are zoomed in too far or too far out, it may not display any data.

   • Solution: Adjust the zoom level of the map to an appropriate range that allows your data to be visible. You can control this in the map's visualization settings.

5. Visual Filters: Filters applied to your report or page can affect what data is displayed on the filled map. If there are filters that exclude the data you want to see, it may result in a blank map.

   • Solution: Check for applied filters in your report and ensure they are not unintentionally excluding the data you want to visualize on the filled map. Adjust or remove filters as needed.

6. Map Legend Settings: The map legend can be configured to display different information about your data. If the legend settings are not set correctly, it may appear as if the map is blank.

   • Solution: Review the legend settings for your filled map and ensure they accurately represent the data you want to display. Customize the legend as needed to provide clarity to your viewers.

Conclusion

A blank filled map in Power BI can be frustrating, but it's typically due to issues with data matching, geocoding, missing or incorrect data, map zoom levels, visual filters, or legend settings. By carefully reviewing and addressing these common causes, you can ensure that your filled maps in Power BI display the intended geographic data and effectively communicate insights to your audience.
