Realtime datalog test from Raspberry Pi. HP 3245A 10V measured with K2001, K2002, 3458A
Please wait for all data to get loaded. It may take 10-30 seconds in worst case.
If some graphs (should be 4) are missing, try to reload page.
Warning, CAVEAT! Some data points in CSV's are missing, but are interpolated on graphs. These interpolated segments do not have REAL DATA! You can see them as very smooth sections on graph. Beware.

Workflow:
* RPI accesses DMMs via GPIB and reads data.* Data is formatted by python script into DSV string and written/append to file on FTP
* DSV-file is visible publicly on https://xdevs.com/datashort/
* Page http://xdevs.com/datalog_mm/ runs D3.js javascript library to read DSV file test.log to input data
* D3.js plots SVG graph online :)
