Anyway, here is the next version 1.2.1.
The only change is that I realized as the number of meters and plotted variables increases, it gets tough to count the variable column position in the output data file. So this version prints out the meter or plotted variable and the column number so that you could enter the column number directly into Gnuplot.
I am working on a three level three phase inverter case next. Hope that will be done in a week.
