How to Remove White Borders Between Excel Pie Chart Slices

Product: Excel
Device & OS: not provided
Scenario: Customizing the visual appearance of an Excel pie chart to improve presentation quality.
Observed behavior: Visible white borders or lines appear between the pie chart slices, creating an unwanted separation gap.

Before you start

Ensure your pie chart is already created and properly selected in your spreadsheet before you attempt to adjust the border formatting.

Solution 1Recommended

Remove Borders Using Format Data Series

This is the quickest way to eliminate the white lines between all pie slices simultaneously.

By default, Excel applies a white border to chart slices to help visually separate the data points. You can easily disable this setting for the entire data series at once.

Select the Data Series

Double-click directly on one of the colored slices in your pie chart to select the entire data series, rather than the outer chart area.

Open the Formatting Pane

Right-click the selected slices and choose 'Format Data Series' from the context menu to open the formatting pane on the right side of your screen.

Access Fill & Line Settings

In the Format Data Series pane, click on the 'Fill & Line' icon (which looks like a paint bucket).

Remove the Border

Expand the 'Border' section and select the 'No line' radio button. The white lines between your pie chart slices will instantly disappear.

Tip: If you still see a border around the entire chart itself, you will need to repeat a similar process for the 'Chart Area'.

Solution 2

Format Individual Pie Chart Slices

Use this method if formatting the entire data series did not work, or if you only want to remove borders from specific slices.

Frequently Asked Questions

Why do my Excel pie charts have white lines by default?

Excel applies a thin white border to pie chart slices by default to help visually distinguish different data points, which is especially useful when adjacent slices have similar colors.

Can I change the color of the slice borders instead of removing them?

Yes. In the Format Data Series pane under the Border section, you can choose 'Solid line' and select a custom color that better matches your chart's design theme instead of selecting 'No line'.

How do I remove the outer border box of the entire pie chart?

To remove the outer rectangular border surrounding your chart, click the empty space inside the chart box to select the Chart Area. Open the Format Chart Area pane, navigate to Border, and select 'No line'.

Will removing the borders affect my chart data or values?

No. Modifying the chart's border settings only changes its visual formatting and appearance. It does not alter the underlying data, formulas, or values in your spreadsheet.
