Making a graduated symbols map

You can create a graduated symbols map using the Layer Properties dialog box.

A graduated symbols map uses equal-interval classification to create graduated color and/or size maps.

Using the equal-interval classification method, the range of attribute values is divided into equal-sized subranges; the features are then classified based on those subranges.

How to make a graduated symbols map:

  1. Click a layer in the legend to make it active.

  2. Click the Layer Properties button.

  3. Click Graduated Symbols.

  4. Click a Field.

  5. Click a number of Classes.

  6. Click a Style.

  7. Click a Start and End Color.

  8. Click a Start and End Size.

  9. Click an entry in the Symbol column to change its color.

  10. Double-click a value in the Label column to select it. Enter a new value.

  11. Click OK to close the dialog box and see the changes.

Tip: For a graduated symbols map, you can change the label of each value by typing a new value in the Label column. Be sure to press Enter after adding each new value.
