Feature display and style

With Esri Maps for SharePoint, you can style your data on the map using different symbols, colors, and sizes to appropriately represent the features. For example, you may want to use different public safety symbols to denote locations of police and fire stations, or use different colors or sizes of a symbol to show locations of major cities according to the population.

When you add data from your business system to the map, Esri Maps for SharePoint creates a layer that appears on the Contents pane and draws the data on the map using a default style. The style can be changed using the options on the Style pane.

How layers are drawn

The Style pane allows you to draw a layer as follows:

  • With a single symbol or color—Draw the features in a layer using the same symbol or color.
  • With different colors—Divide your data into groups and show each with a different color.
  • With different-sized symbols—Divide your data into groups and show each with a different size.

For layers containing point features, there are two different types of symbols you can use to style your data: icons and shapes.

  • Icons—Standard, Business and Facilities, Public Safety, Transportation, People and Places, Public Safety and Health, and Outdoor Recreation
  • Shapes—Circles, Crosses, Diamonds, Squares, and Xs

For layers containing polygon features, you can style your data using different colors.

If you Add data from ArcGIS that contains line features, you can change the style of the line features by choosing from different line types and colors and changing the line thickness.

For more information, see Style points, Style lines, and Style polygons.

Grouping methods

If you decide to style a layer using either different colors or different-sized symbols (for point features only), you will be asked how you want to group your data and what field (or attribute) to use to group it. If you choose to group your data by categories, your data will be grouped and styled based on a common value for the field (or attribute) you chose for grouping (for example, business types such as retail or wholesale).

If your layer has numeric fields, you can choose to group your data by number ranges. For this grouping option, you must choose a classification method. Each classification method takes your data and divides it into classes (groups). Classification method options include Equal Interval, Natural Breaks, and Quantile. The value at which a feature is placed into a different class is often referred to as a class break. The way in which class breaks are determined by each grouping method is discussed below.

Equal Interval

With the Equal Interval classification method, the range of all of your data values are divided into equal-sized subranges. With Equal Interval classification, you specify the number of intervals (or subranges), and Esri Maps for SharePoint automatically determines how to divide the data. For example, if you specify three classes for a field whose values range from 0 to 300, Esri Maps for SharePoint creates three classes with ranges of 0–100, 101–200, and 201–300. Equal Interval is best applied to familiar data ranges, such as percentages and temperature. This method emphasizes the amount of an attribute value relative to other values. For example, it shows that a store is part of the group of stores that make up the top one-third of all sales.

Natural Breaks

Natural Breaks classes are based on natural groupings inherent in the data. Class breaks that best group similar values and maximize the differences between classes are identified. The features are divided into classes whose boundaries are set where there are relatively big differences in the data values. Natural Breaks classification is good for mapping data values that are not evenly distributed as it places clustered values in the same class.


In Quantile classification, each class contains an equal number of features (for example, 10 per class or 20 per class). A quantile classification is well suited to linearly distributed data. It is useful when you want to emphasize the relative position of a feature among other featuresfor example, to show that a store is in the top quarter of all stores by sales. Quantile classification assigns the same number of data values to each class. There are no empty classes or classes with too few or too many values. Because features are grouped in equal numbers in each class using quantile classification, the resulting map can often be misleading. Similar features can be placed in adjacent classes, or features with widely different values can be put in the same class. You can minimize this distortion by increasing the number of classes.
