Symbology categorized 2 fields with categorized information
I have a pipelines feature class that I need symbolized. Each pipe has a diameter (inches) and a type (either Other, Critical, or Backbone). I need to symbolize the pipes by diameter range and by type. For example:
The "Other" pipelines will be gray in color, but the size of the line symbol depends on the pipe diameter.
.75-8" diameter = thin gray line
8.1 - 16" diameter = thicker gray line
16.1-24" diam = even thicker gray line
24.1"-108' = thickest gray line
The "Backbone" piplines will be blue in color, but the size of the line symbol depends on the pipe diameter parameters listed above.
The "Critical" pipelines will be red in color, but the size of the line symbol depends on the pipe diameter parameters again listed above.
Is there a way I can set the symbology to take care of this without having to copy the layer multiple times or creating separate feature classes?
Let me know if you need more information and thanks in advance.
Mapping Center Answer:
Creating separate feature classes is one solution though as you rightly point out you have to split your data up to do it this way.
An alternative is to create a new field in your data and assign an integer value (it doesn't matter what values you use) based on a boolean calculation. So, for instance, when calculating the value for the new field you might specify .78-8" AND other = 1, 8.1-16" AND other = 2 etc... You have 4 separate diameters and three different types so you'll need 12 different integer values to represent the number of possible variations.
You then just symbolize your new integer field using the symbols you want.
