Formating Legend Labels for Symbology by Quantities

ArcMap legend labels always seem to come out in an undesired format and always need adjustments. For layers that are symbolized based upon quantity there is an easy way to change the number format.  (If you are not sure how to symbolize by quantity, read ArcMap Symbology by Quantity.) When symbolizing quantities that need format adjustments, you can edit each label individually or use the built in format option. To use this option:

1. Open Layer Properties for desired layer.

2. Symbolize layer based upon quantity.

3. Left Click the Label Heading.

Notice the number of decimal places.

4. Choose Format Labels…

5. Make desired changes.

*Note: You can change number type such as currency, direction, percentage, rate, fraction, angle, etc.  There is also the ability to round and set alignment.  Also notice the additional options available.

6. Click Ok.

Results are shown and updated in the legend. Notice that only one decimal place is now shown.  Remember that this is also updated in the legend.
