i am trying to apply a symbology to multiply layers that i have created from one feature class.
The original feature class is used to create several sub layers see
layer loop
this involves using arcpy.MakeFeatureLayer_management
Before using arcpy.SaveToLayerFile_management
i would like to apply some symbology to the layers that have been created. I thought if i took the original feature class and applied some the desired symbology and then saved this as a layer file. This could be used when using the Apply Symbology From Layer
The layers were made and then the symbology was applied.
But when drag the layers into ARC MAP , they all have the identicaly symbology showing in the TOC.
The actually polygons are coloured up correctly.
Example _ Original feature class symbology
1-100 = ORANGE
101 – 200 = RED
201- 300 = BLUE
301 – 400 = GREEN
401 -500 = PURPLE
Created layer value
10
200
300
In the TOC the symbology contains all of the items within the the template
How the layer is showing in the TOC
1-100 = ORANGE
101 – 200 = RED
201- 300 = BLUE
301 – 400 = GREEN
401 -500 = PURPLE
Desired Output
1-100 = ORANGE
101 – 200 = RED
201- 300 = BLUE
Is it for the TOC to show the desired output. My worry is that someone might look at the symbology and assume there are data points. When actually none exist

Since you know exactly what you want your new symbolization to be, I would suggest saving a layer file with that symbolization. In arcmap, add a test layer to your table of contents, and symbolize it as desired (1-100 orange, 101-200 red, 201-300 blue). Then right-click on the layer in the table of contents and 'Save As Layer File...' This lets you save the symbology in a
.lyr
file.Now you can reference this layer file in your code for your final output.
for example:
