And then load from text file sar20_new

I correctly see the graphs.
I need yet to crosscheck better if text values match the graph but a preliminary check seems ok.
So we can check OS version and depending on it we can provide a pre-transformed temporary file and have the jar work on it instead that on the original one...

Can anyone check and let me know if it works for him/her too?
