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

    import os
import units

def write_legend_settings(result,filepath,guid):
    min_qty = result.MinimumOfMinimumOverTime
    max_qty = result.MaximumOfMaximumOverTime
    minimum = units.ConvertUnit(min_qty.Value, min_qty.Unit, "Pa")
    maximum = units.ConvertUnit(max_qty.Value, max_qty.Unit, "Pa")
    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)
    with open(filepath,'w') as f:
        f.write(template)


def import_settings(filepath):
    cmds = '''
var filePath = "{}";

var refLegendStyleMgr = WB.ScriptEngine.Engine.CreateActiveXObject(WB.ScriptEngine.Engine.GenWBProgId("AnsCoreObjects.AnsLegendStyleManager"));
var callback = WB.ScriptEngine.Engine.CreateActiveXObject(WB.ScriptEngine.Engine.GenWBProgId("AnsCoreObjects.AnsDelegate"));
callback.AddCOM(this, "OnOverwriteStyle");

refLegendStyleMgr.ImportStyles(filePath, callback,true);
'''.format(filepath.replace('\\','\\\\'))

    ExtAPI.Application.ScriptByName("jscript").ExecuteCommand(cmds)


maxstress=ExtAPI.DataModel.Project.Model.Analyses[0].Solution.Children[1]
folder = r'D:\Temp'
legend_xml = os.path.join(folder,'legend_settings.xml')
guid="{79E20481-F97C-46CF-8389-A1B633E3E555}"

write_legend_settings(maxstress,legend_xml,guid)

import_settings(legend_xml)

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

ExtAPI.Application.ScriptByName("jscript").ExecuteCommand(cmds)

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

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

    with

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

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