simple time series plot
The preferred format for time series will be something like this:
Sensor1 Sensor2 Sensor3
T1 Read1_1 Read2_1 Read3_1
T2 Read1_2 Read2_2 Read3_2
T3 Read1_3 Read2_3 Read3_3
if you can get that. CSV separations are nice but not as essential as
the columnar organization. (It's possible with your other formats, but
it will be much harder)

Thanks for your reply! As I write the script to export the data from the database myself, I'm free to sort the data (almost) at will. I can either export to CSV in the form of sensor1 timestamp1, reading1, timestamp2, reading2, timestamp2, reading2... sensor2 timestamp1, reading1, timestamp2, reading2, timestamp2, reading2... OR sensor1 timestamp1, timestamp2, timestamp3, ... reading1, reading2, reading3, ... sensor2 timestamp1, timestamp2, timestamp3, ... reading1, reading2, reading3, ... What is easier to read into a matrix? Sorry for asking such a stupid question. But I just couldn't figure out how to read in the CSV into a data structure that I could plot afterwards.
