    I have saved many Legends settings in xml files. I can access them interactively using the "Manage Named Legends" RMC on the results legend -> Named Legends -> Manage -> Import

    Also once the legends settings are loaded. How do I pick one from the list in my mechanical script?

    Thanks a lot

      1. import os
      2. import units
      3.  
      4. def write_legend_settings(result,filepath,guid):
      5.     min_qty = result.MinimumOfMinimumOverTime
      6.     max_qty = result.MaximumOfMaximumOverTime
      7.     minimum = units.ConvertUnit(min_qty.Value, min_qty.Unit, "Pa")
      8.     maximum = units.ConvertUnit(max_qty.Value, max_qty.Unit, "Pa")
      9.     template = '''<?xml version="1.0" encoding="UTF-8" standalone="no" ?><styles version="11"><style colorMode="0" contourCount="9" editable="-1" factoryStyle="0" guid="{}" independentBands="0" log="0" mode="1" name="0_9999" namedStyle="-1" numericMode="1" orientation="1" significantDigits="5" transparency="0" unitless="0"><band color="0" colorAuto="-1" label="" value="{}" valueAuto="0"/><band color="0" colorAuto="-1" label="" value="0" valueAuto="-1"/><band color="0" colorAuto="-1" label="" value="0" valueAuto="-1"/><band color="0" colorAuto="-1" label="" value="0" valueAuto="-1"/><band color="0" colorAuto="-1" label="" value="0" valueAuto="-1"/><band color="0" colorAuto="-1" label="" value="0" valueAuto="-1"/><band color="0" colorAuto="-1" label="" value="0" valueAuto="-1"/><band color="0" colorAuto="-1" label="" value="0" valueAuto="-1"/><band color="0" colorAuto="-1" label="" value="0" valueAuto="-1"/><band value="{}" valueAuto="0"/></style></styles>'''.format(guid,minimum,maximum)
      10.     with open(filepath,'w') as f:
      11.         f.write(template)
      12.  
      13.  
      14. def import_settings(filepath):
      15.     cmds = '''
      16. var filePath = "{}";
      17.  
      18. var refLegendStyleMgr = WB.ScriptEngine.Engine.CreateActiveXObject(WB.ScriptEngine.Engine.GenWBProgId("AnsCoreObjects.AnsLegendStyleManager"));
      19. var callback = WB.ScriptEngine.Engine.CreateActiveXObject(WB.ScriptEngine.Engine.GenWBProgId("AnsCoreObjects.AnsDelegate"));
      20. callback.AddCOM(this, "OnOverwriteStyle");
      21.  
      22. refLegendStyleMgr.ImportStyles(filePath, callback,true);
      23. '''.format(filepath.replace('\\','\\\\'))
      24.  
      25.     ExtAPI.Application.ScriptByName("jscript").ExecuteCommand(cmds)
      26.  
      27.  
      28. maxstress=ExtAPI.DataModel.Project.Model.Analyses[0].Solution.Children[1]
      29. folder = r'D:\Temp'
      30. legend_xml = os.path.join(folder,'legend_settings.xml')
      31. guid="{79E20481-F97C-46CF-8389-A1B633E3E555}"
      32.  
      33. write_legend_settings(maxstress,legend_xml,guid)
      34.  
      35. import_settings(legend_xml)
      36.  
      37. cmds = '''
      38. DS.Graphics.GfxUtility.Legend.ApplyLegendStyle("{}")
      39. '''.format(guid)
      40.  
      41. ExtAPI.Application.ScriptByName("jscript").ExecuteCommand(cmds)
      42.  

      Note that in newer versions of Ansys (~2024), it may be necessary to replace

      1. cmds = '''
      2. DS.Graphics.GfxUtility.Legend.ApplyLegendStyle("{}")
      3. '''.format(guid)

      with

      1. cmds = '''
      2. DS.Graphics.GfxUtility.Legend.LegendStyle="{}"
      3. '''.format(guid)

      @GabrielArias, I agree. @sachinverghese and @Pierre Thieffry, here is an example where Mechanical scripting users still need to rely on Jscript.
