Question details

The user is trying to determine if there is a hardcoded 20-item limit for legends in Excel Maps because their chart is not displaying all expected data points.

Product
Microsoft Excel
Device & OS
not provided
Scenario
Creating an Excel Maps chart to display sales territories by state.
Observed behavior
The chart legend fails to display all of the expected territory names, cutting off items regardless of the data source.
Before you start

Before troubleshooting, ensure that your entire data range is properly selected and that the legend box has not been accidentally resized, which could hide entries.

Solution 1Recommended

Resize the Legend Box or Adjust Font Size

Often, legend items are hidden because the physical legend box is too small to display all entries, rather than a hardcoded 20-item limit.

There is no officially confirmed general 20-item legend limit in Excel Maps. Most commonly, visual truncation happens when the chart area rendering cannot accommodate the font size and the number of items.

1
Select the legend

Click directly on the legend within your Excel Map chart to reveal its bounding box.

2
Resize the box

Click and drag the sizing handles (the small circles on the corners and edges) to make the legend taller or wider to accommodate more items.

3
Decrease font size

Right-click the legend, select 'Font', and reduce the font size. This will allow more text to fit within the designated legend space.

No Hardcoded Limit: Microsoft support experts confirm there is no known 20-item limitation in Excel Maps. Missing items are almost always due to spatial constraints or data selection errors.

Frequently Asked Questions

Is there a maximum number of data points Excel Maps can plot?

While Excel Maps does not have a strict 20-item limit for legends, performance may degrade or visual elements might overlap if you plot thousands of geographical data points. It is best to summarize data before mapping.

Why does my Excel Map chart show blank or missing territories?

Blank areas typically occur if the geographic names (like states, counties, or postal codes) are misspelled, ambiguous, or not recognized by the Bing Maps engine used by Excel. Ensuring standard nomenclature resolves this.

How do I fix overlapping text in an Excel chart legend?

You can fix overlapping or truncated text by resizing the overall chart area, dragging the edges of the legend box to expand it, moving the legend to the bottom or right side of the chart, or decreasing the font size of the legend text.
