Easily create dot density thematic maps
Overview: It can often be convenient to view thematic maps as clustered points. This type of visual output is a logical and accurate representation of data occurring in a non-continuous distribution.
Vertical: Any
Key Tools Used: Formula Tool (ST_Random Point spatial function), Generate Rows
Required Input: As inputs, the Dot Density macro requires two fields: geography with an associated value and a configuration of the number of dots per value. Determining the appropriate number of dots per value may require some trial and error to produce desirable results. Knowing the min, max, and median values associated with the base geographies would help you to determine and optimal dots per value. This coupled with the size of dots on the map will greatly affect the aesthetic of the mapping.
I'm trying to get the dot density macro for work but I keep getting an error message with the file input. The file path from the download is C:\Documents and Settings\rsnow\My Documents\SRC Documents\Dot Density\Sample Input.yxdb, but I don't have this database. Any help?
