Wie fügt man eine Legende zu einer Ebene im ModelBuilder hinzu

Liebe alle!<\/P>

<\/P>

Ich versuche, eine Legende zu einer Ebene im ModelBuilder hinzuzufügen. Die Hilfeseiten sagen, dass ich das Werkzeug "Apply Symbology From Layer" verwenden muss. Ich habe meine Symbology Layer gespeichert, aber sie enthält meine Legende nicht (soweit ich verstanden habe, kann eine Legende nur in einer Map-Datei gespeichert werden). Könnten Sie mir bitte erklären, wie ich das richtig mache?<\/P><\/BODY><\/HTML>

If I understood correctly, you want to add legend with model builder.Apply Symbology From Layer extracts Symbology from a layer ( which is a layer you prepared before) to another layer which does not have symbology. 

As far as I know , there is no tool to include legend in model builder but you could create a script "to add legend" in python and make a tool with that script. Then you can add it to your model. Here same code you can use to create layer from shp and add sybology.

import arcpy

symbologyLayer=r"C:\.....\sembology.lyr"  # if you want to assign same layer format all the time this can be a path to your symbology

LabelExpression="[Fieldyouwantolabelwith]"  #if you want label you can make it parameter if not you do not have to use this label parts

K_shp= arcpy.GetParameterAsText(0)  ### your shp file  you want to assign symbology

## those above will be your parameters

mxd = arcpy.mapping.MapDocument(r"C:\......\my.mxd")

#or mxd = arcpy.mapping.MapDocument("CURRENT")

df = arcpy.mapping.ListDataFrames(mxd)[0]

arcpy.MakeFeatureLayer_management(K_shp,"Layername")

lyr1= arcpy.mapping.Layer("Layername")

arcpy.ApplySymbologyFromLayer_management (lyr1, symbologyLayer)

lyr1.labelClasses[0].expression = LabelExpression

lyr1.showLabels = True

legend = arcpy.mapping.ListLayoutElements(mxd, "LEGEND_ELEMENT", "Legend")[0]

legend.autoAdd = True

arcpy.RefreshActiveView()

arcpy.mapping.AddLayer(df, lyr1, "BOTTOM")
