A curiosity, but what device extracts the data? I use Veusz for analyzing real-time data, and I am very well. But normally use an intermediate program (written in Java) that collects data from Arduino devices or Rasp Berry, and resynchronize them in the time domain, then this program writes data directly to a CSV file which is periodically read by Veusz. I note that it is important to synchronize in this way, otherwise the data are therefore not comparable with each other. I will be happy to publish my program if I find people interested in using it. I've never done an equivalent in Python, because I very little use such language. My program works easily with a record number of around 1E6, each record is made up of about 20-40 fields.
