When using the following config generated by the plugin code snippet:

Code:

post { 
    always {
         plot(group: 'percent',
                csvFileName: 'plot-54408a16-8d7e-446a-824b-78ebd734eb9a.csv', 
                propertiesSeries: [file: 'ppglobal.properties', label: 'Protocol_Processor'],
                style: 'line', title: '4.1.0', useDescr: true, yaxis: '%', yaxisMaximum: '',   
                yaxisMinimum: '',
                exclZero: true, 
                keepRecords: true, 
                logarithmic: false, 
                numBuilds: '90')
       }
}

Error:

 
WorkflowScript: 50: Missing required parameter: "csvSeries" @ line 50, column 11.
plot csvFileName: 'plot-54408a16-8d7e-446a-824b-78ebd734eb9a.csv',

Is this expected behavior ?
