How to Format Power BI Map
Please click on the Format button to see the list of formatting options that are available for this map.

Format Power BI Map Data Colors
While we were creating this map, we added the Order Quantity as the Color Saturation, and that’s why we see the Diverging option under the Data Colors. Please change the Minimum, Center, and Maximum colors as per your requirements.

If you removed the Order Quantity from the Color Saturation, the Data Colors section shows you the colors of each bubble, as we shown below.

Let me add the Order Quantity to Color Saturation again

Format Power BI Map Category Labels
Map Category labels mean names that represent each bubble or circle. By toggling the Category labels option from Off to On, you can enable these labels.
From the screenshot below, you can see that we change the Color to Black and the Text Size to 14. If you want, you can add the background color as well.
