Using stacked charts
Stacked charts are used to display amounts by category, for example, to view population broken down by age categories. Each feature is annotated with a chart that shows the amounts in each category, such as in the example shown here.
Charts are most effective when mapping no more than 30 features. Otherwise, the patterns on the map will be difficult to see. Typically, use just a few categories on a chart.
- Right-click the layer you want to draw showing quantitative values with stacked charts and click Properties.
- Click the Symbology tab on the Layer Properties dialog box.
- Click Charts and click Stacked.
- Under Field Selection, click the numeric field(s) that you want to map. Then, use the arrow buttons to add and remove fields to the field list.
- Optionally, select a Normalization field to normalize the data. The values in this field will be used to divide the value fields to create ratios.
- Use the Color Scheme drop-down list to select the color ramp that you want to use.
- If you want to prevent overlapping charts, check Prevent chart overlap.
- Optionally, you can click the Exclusion button and use a SQL expression to exclude values (such as outliers).
- Click Size.
- Click OK.
You can double-click an individual symbol in the list to change its properties.
