Error setting symbol template for the GraduatedSymbolsRenderer class from ArcPy in ArcGIS Pro.

対処法

Add a layer file (template) that has the renderer set for the point FC, then change its data source to your correct point FC, update the classificationField to refresh the stats for the new layer and remove the original, replaced layer.

p = arcpy.mp.ArcGISProject('current')

m = p.listMaps('Map')[0]

lyr1 = m.listLayers('SimplePtLayer')[0]

lyrFile = arcpy.mp.LayerFile(r"C:\Temp\GraduatedColors_Point.lyrx")

lyr2 = m.addLayer(lyrFile)[0]

lyr2.updateConnectionProperties(lyr2.connectionProperties, lyr1.connectionProperties)

sym = lyr2.symbology

sym.renderer.classificationField = 'Elevation' #resets field and stats

#Update symbol template - keep in mind lyrx could already have it.

symTemp = sym.renderer.symbolTemplate

symTemp.applySymbolFromGallery('Square 1')

sym.renderer.updateSymbolTemplate(symTemp)

#apply changes

lyr2.symbology = sym

#remove original layer

m.removeLayer(lyr1)
