You can visualize the data displayed on a map by setting rules to control color, size or marker type for all map elements on a layer. You can set three types of rules depending on the type of layer in use.

  1. Color Rule

    Color Rule is set to fill colors for map elements like  polygons, markers (points or polygon center points) and lines while using a Polygon, Point or Line layer.
    Color Rule provides four options:
    1. Apply Appearance Settings : Use the default appearance settings that are set in the Appearance page of the map layer dialog. 
    2. Visualize data by using color palette : This option uses an in-built palette that you specify. Based on related analytical data, each map element is assigned a different color from the palette.
    3. Visualize data by using color ranges : This option, combined with the start, middle, and end colors that you specify on this page and the options that you specify on the Distribution page, divide the related analytical data into ranges. The report then assigns the appropriate color to each map element based on its associated data and the range that it falls into. For example, in a map which uses color to display temperatures on a scale of 0 to 100, low values are blue to represent cold and high values are red to represent hot.
    4. Visualize data by using custom colors : This option uses the list of custom colors that you specify. Based on related analytical data, each map element is assigned a color from the list.

    To visualize polygons, lines or markers using color ranges

    To visualize polygons, lines or markers using custom colors 

  2. Marker Rule

    Marker Rule is set on markers that represent points or polygon center points on a map while using a Point layer.
    Marker Rule support two options:
    1. Use a default marker type : You specify one of the available marker types.
    2. Visualize data using markers : This option uses a set of markers in an order in which you want them to be used. Marker types include Rectangle, Circle, Diamond, Triangle, Trapezoid, Star, Wedge, Pentagon, PushPin and Image.

    To visualize points using default marker type

    To visualize points using specific marker types

    To visualize points using Image as marker type

  3. Size Rule

    Size Rule is set on markers, polygon center points or line width while using a Polygon, Point or a Line layer.
    Size Rule support two options:
    1. Use a default marker size or Use a default line width : You specify the marker size or line width in points.
    2. Visualize data by using size or Visualize data by using line width : In this option, you set the minimum (start) and maximum (end) sizes or width for marker or line, specify the data field to be used for varying the marker size or line width and then specify the distribution options to apply to that data.

    To set Size Rule for markers and line width

    To visualize marker or line using default marker size or line width

    To visualize marker or line using specific marker size or line width 

Distribution Options

The distribution values are used by the rules to differ the map element display values.

To create a distribution of values, you divide your data into ranges by specifying the distribution method, the number of sub-ranges, and the range start and end values.
