Problem with plotting graph via serial connection

I have loaded following sketch into my arduino Uno board and connected to PC via serial connection.But ,when i click serial plotter to get the graph of my data…the graph is not visible in arduino IDE serial plotter.How to get graph of each parameter in single serial plotter. PLEASE DO HELP ME OUT

emon1.calcVI(20,2000); // Calculate all. No.of half wavelengths (crossings), time-out
emon1.serialprint(); // Print out all variables (realpower, apparent power, Vrms, Irms, power factor)

float realPower = emon1.realPower; //extract Real Power into variable
float apparentPower = emon1.apparentPower; //extract Apparent Power into variable
float powerFActor = emon1.powerFactor; //extract Power Factor into Variable
float supplyVoltage = emon1.Vrms; //extract Vrms into Variable
float Irms = emon1.Irms; //extract Irms into Variable
