Is there a bug in the arcpy symbology rendering or is this a syntax issue? I am trying to change the outline of my symbology rendering output to no color but I can't seem to change the outline color, only the point symbol color changes. Does anyone else have the same issue? Please see my script below. I know the last number is for opacity, which is the opposite of Transparency, but it doesn't seem to make a difference when I change the opacity number, because the outline color remains black...Thanks for your help!</P><LI-CODE lang="c">#Add spatial join layer to the current map p = arcpy.mp.ArcGISProject('CURRENT') m = p.listMaps('map')[0] layer = Comp.getOutput(0) m.addDataFromPath(layer) #Format symbology rendering l = m.listLayers(Comp_Name)[0] sym = l.symbology if sym.renderer.type == 'SimpleRenderer': sym.updateRenderer('GraduatedColorsRenderer') sym.renderer.classificationField = Comp_Field sym.renderer.classificationMethod = 'NaturalBreaks' sym.renderer.breakCount = 7 #Updating Symbology Rendering for brk in sym.renderer.classBreaks: brk.symbol.size = 6 brk.symbol.outlineColor = {'RGB' : [0, 0, 0, 0]} #Show symbology updates l.symbology = sym</LI-CODE> Tue, 04 Oct 2022 18:17:47 GMT tzz_12 2022-10-04T18:17:47Z https://community.esri.com/t5/python-questions/symbology-rendering-question-color-outline-to-null/m-p/1217170#M65710 <P>Hi Everyone,&nbsp;</P><P>I am hoping ESRI staff will also respond to this post.
