I would probably split up the x and y values into different fields. Assuming each value has some time associated with it:
timestamp,x,y timestamp,float,float T,, 12/30/10 09:00,x, 12/30/10 10:00,x, 12/30/10 11:00,x 12/30/11 00:00,,y It's okay to send in a row with no data for a field, so you could pass the x values at each time they actually occur, and the summarized y value at the end of the day. The only thing I'm worried about is you having enough data. Four data points a day is not a lot, and it will take a long time for NuPIC to learn the patterns unless you have a lot of historical data to pass it. --------- Matt Taylor OS Community Flag-Bearer Numenta On Tue, Jul 8, 2014 at 5:41 AM, R.
