I have a blank map. And I have a shapefile. I would like to add the shapefile to the map document, change its colour to grey and then save the map document.
My plan is to make a layer from the shapefile (MakeFeatureLayer_management
), add the resulting layer to the map document (mapping.AddLayer
) and then change its colour using ApplySymbologyFromLayer_management
.
This is my code so far:
import arcpy, os
### Set directory
arcpy.env.workspace = ...
arcpy.env.overwriteOutput = 1
### Define inputs
yellow = "symbology/yellow.lyr"
# Set map document
mxd_city_year = arcpy.mapping.MapDocument(r"...\blank_map.mxd")
DF = arcpy.mapping.ListDataFrames(mxd_city_year)[0]
# Add layers
arcpy.MakeFeatureLayer_management("states/continental_US.shp", "us")
basis = arcpy.mapping.Layer("us")
arcpy.mapping.AddLayer(DF, basis, "AUTO_ARRANGE")
arcpy.ApplySymbologyFromLayer_management(basis, yellow)
# Save map
mxd_city_year.saveACopy("thresh_" + city + "_" + year + ".mxd")
The code runs through (no error). However, in the resulting map document the colour still seems to be random.
What is my mistake?
