https://community.esri.com/t5/python-questions/why-is-the-arcpy-script-for-symbology-rendering/m-p/1221353#M65840 <P>I noticed that the arcpy script to change the symbol outline for symbology rendering does not work in ArcGIS Pro v. 2.8. Using the python console to troubleshoot my python script, I realized that&nbsp;</P><LI-CODE lang="python">if sym.renderer.type == 'SimpleRenderer': sym.renderer.symbol.color = {'RGB' : [0, 0, 0, 0]}} sym.renderer.symbol.outlineColor = {'RGB' : 0, 0,0, 0]}</LI-CODE><P>&nbsp;will change the color of the point symbol, but not the point symbol outline. The same for the graduated color rendering,&nbsp;</P><LI-CODE lang="c">for brk in sym.renderer.classBreaks: brk.symbol.outlineColor = {'RGB' : [0,0,0,0]} brk.symbol.color = {'RGB':[0,0,0,0]}</LI-CODE><P>It doesn't matter what color RGB I change it, the outlineColor and color will only result in the symbol color change. The outline color does not work. I was wondering if there is a way around this without using applysymbologyfromlayer gp tool ? I have script to create a customized my graduate color rendering and using the tool will change my graduate color rendering. Thanks for your help!</P> Wed, 12 Oct 2022 23:49:08 GMT tzz_12 2022-10-12T23:49:08Z https://community.esri.com/t5/python-questions/why-is-the-arcpy-script-for-symbology-rendering/m-p/1221353#M65840 <P>I noticed that the arcpy script to change the symbol outline for symbology rendering does not work in ArcGIS Pro v. 2.8.
