- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Customizing the visual formatting of map charts to ensure multiple charts have identical country border colors.
- Observed behavior
- Two map charts with seemingly identical settings display different border colors until the chart outline formatting is manually adjusted.
Ensure your Excel workbook containing the map chart is open and the chart area is selectable. Click directly on the map regions to ensure you are modifying the data series rather than the outer chart frame.
Change Map Chart Border Colors Using Format Data Series
Use the right-click Format Data Series menu to manually set a solid outline color for your map chart borders.
By default, Excel map charts may apply varying theme colors. To ensure two map charts look identical, you must manually apply the same solid line border color to the data series of both charts.
Click directly on the mapped geographical area (the countries or regions) inside your chart to select the Data Series.
Right-click the selected area and choose 'Format Data Series' from the context menu to open the formatting pane on the right.
In the Format pane, click the 'Fill & Line' icon (the paint bucket) and expand the 'Border' section.
Select 'Solid line' and choose your desired outline color from the Color dropdown. Repeat these exact steps on your second map chart to ensure the border colors match perfectly.

Frequently Asked Questions
Why are my map chart borders not changing color?
This typically occurs if you have selected the overall 'Chart Area' or 'Plot Area' instead of the 'Data Series'. Ensure you click directly on the colored map regions before changing the outline color in the formatting pane.
Can I change the border thickness of an Excel map chart?
Yes. Once you are in the 'Format Data Series' pane under the 'Fill & Line' settings, you can adjust the 'Width' value in the Border section to make the country outlines thicker or thinner.
Is it possible to remove the country borders entirely?
Yes. Open the formatting options for your map chart's data series, go to the Border section, and select 'No line'. This will completely remove all borders between the mapped regions.
Why do identical map charts look different?
Excel sometimes applies dynamic theme settings to map charts based on when they were created or data updates. Manually setting the 'Solid line' border color on both charts overrides these dynamic themes and forces consistency.
