Variable Symbol Maps or Bubble Maps

wholmstead

Hello:

I am new to the forum so please excuse me if this question has been asked before. I would like to create a variable size symbol map or sometimes called a bubble map. This map is used to display points with variable values. The variable values are represented by symbols of different sizes. For instance:
1=10 pixel circle
2=20 pixel circle etc.

Any ideas?

Thanks,

Wayne

Wayne,

Currently the only way to get circle symbols of various (like for a bubble map) is to import a file (like a CSV text file or ASCII file) with the POINT_SYMBOL field set up to a special name to represent a circle of a particular color with a particular size. Here is the documention of the field format:

5. SYMBOL, POINT SYMBOL, POINT_SYMBOL –if this value matches one of the following values, that symbol will be used for the point feature, attribute names are ignored for line features. The symbol name should either exactly match one of the symbol names in Global Mapper, or be of the form DOT_CUSTOM_<SIZE>_<RED>_<GREEN>_<BLUE> or SQUARE_CUSTOM_<SIZE>_<RED>_<GREEN>_<BLUE> where the <SIZE> value is the radius in pixels of the dot or square, and the <RED>, <GREEN>, and <BLUE> values represent the color to use.

For example, to create a red circle 5 pixels in radius, use a POINT_SYMBOL value of DOT_CUSTOM_5_255_0_0.

Let me know if I can be of further assistance.

Thanks,

Mike
