How to group values after Unique symbology classification in arcpy?

ManjariGoyal

I am trying to group values through arcpy. So, I would like to group all approved together and all reject together. But I am not sure how to do it through Python script. Below is the part of the script:

arcpy.MakeFeatureLayer_management(FC3, r"C:\Users\Documents\NGN\Regions\MW_Decision.lyr")
layer3 = arcpy.mapping.Layer(r"C:\Users\Documents\NGN\Regions\MW_Decision.lyr")
Sym_layer3 = r"C:\Users\Documents\NGN\Symbology layer new\MW_Decision.lyr"
arcpy.ApplySymbologyFromLayer_management (layer3, Sym_layer3)
arcpy.mapping.AddLayer(df, layer3, "AUTO_ARRANGE")
lyr3 = arcpy.mapping.ListLayers(mxd, "", df)[0]
lyr3.visible = False
lyr3.name = "MW_Decision"

Any help is appreciated.

Hi Manjari,

In the Layer properties under the Symbology tab, select all the approved symbols using the Shift key, right click on the selected symbol rows and select Group Values. This will condense all selected symbols into one symbol set which you can modify. You will need to do the same for the rejected symbols as well. Save this symbol configuration with your Sym_layer3 and it will get applied to the MW_Decision.lyr when you run your script. I hope this helps.

Thanks
