How I can show selected properties in a Line Chart Widget (Mashup)

I have accomplished following your suggestion and works,,,, but I suspect that should be a shorter way.......

var modelProperties = Resources['InfoTableFunctions'].CreateInfoTable({infoTavleName: "modelProperties"});

modelProperties.AddField({name: "name", baseType: "STRING"});

modelProperties.AddField({name: "description", baseType: "STRING"});

modelProperties.AddRow({name: "PreheatTemperature"});

var data = me.QueryNamedPropertyHistory({

    propertyNames: modelProperties,

    maxItems: 1000

});

result = data.ToJSON();

or this one:

let data = me.QueryNumberPropertyHistory({
"propertyName": "PreheatTemperature"
});

data.RemoveField("id");

result = data.ToJSON();

});

result = data.ToJSON();
