I have a CSV with lines like this :

2015-03-18 17:05:00 , 9002, 1305.71296296

I have a chart built from a selection of the data. The date column (#1) is excel-formatted to suit the input.

However the time axis comes up as either a series of meaningless incremental data points or as a series of the same date/time i.e. 12:00:00 AM.

Any ideas?
