[GIS] Showing one feature with two unique values as one symbol in ArcMap legend

arcgis-10.4arcgis-desktoparcmaplegend

I am working in ArcMap 10.4. I have one feature that has two unique values, one is "simple fill" blue the other value is "10% simple hatch". I need to show the 2 values in the map but would like to only show the solid hatch in the legend. I know I could separate the feature and then just remove one from the legend.

Is there another way?

AFAIK legends act on the layer level, not the symbol class level (other than using view extent option to show classes). You are right, you can copy/paste the layer and leave the new one out of the legend. Or you can convert the legend to graphics and delete the legend elements manually.

[GIS] ArcMap Symbology: Assign Color by one attribute, symbol by other attribute

You could definitely do as Johns describes and create an additional field to be your symbol field based on the other three attributes. This could be done by using the field calculator with VB or python. Set the parser as Python, Click "Show Codeblock" For example:

Using if and else statements you can populate your new symbology field with integers or text. Based on this text, you can set your symbology

def symbology (field1, field2, field3):
 #if your 1st field is equal to "sometext" and field 2 is equal to 0.25 populate symbology field with one
  if (field1 == "sometext" and field2 == 0.25):
    return 1
  elif (field1 == "PINE" and field3 > 10):
    return 2
   #if none of the above conditions are met, return 3
  else:
    return 3

under your new field = write:

symbology(!field1!, !field2!, !field3!)

As an additional note, make sure none of your if/else conditions overlap or your won't get the correct values!
