Hatch Map

image\hatch.gifHatch maps use colors or patterns to show the distribution of different classes of data. Hatch maps color code boundary objects based on the associated data value. Data values are placed in classes defined by data ranges, and one color or pattern is associated with each class. You can use color and fill patterns to define classes for areas. For curves and symbols, colors define the classes.  


Creating and Editing a Hatch Map

In a new plot window, choose the Map | Create Map | Hatch command . The Import Boundary File dialog is displayed prompting you to select the boundary file to use for the map.


See Creating and Editing Thematic Maps for more information on creating a hatch map, changing a hatch map to another map type, and changing map properties.

Map Page

The Map page in the Property Manager has properties unique to hatch maps.


Edit hatch map properties in the Map page of the Property Manager.



Hatch maps group data values into classes. All boundaries in a single group use the same properties so it is easy to tell which boundaries are in the same data class on the map. Each group is assigned unique coloring or shading so you can tell the relative differences in data values by glancing at the map. You can have from one to 100 data classes on your map. The Classes group allows you to specify the classes.


Select By data or By text in the Binning method list to use numeric values or text for classification.


Click the button near Classes to change the class bin properties in the Data Classes or Text Classes dialog.


Hatch Draw Type

The General group contains options for the display of the map hatching.
