Line Chart Help

[Mark68]

I have some data with 3 values as follows -

03/09/2014 11:04:37 4.4727294
03/09/2014 11:04:49 12.4435546
03/09/2014 11:05:42 4.5426314
03/09/2014 11:05:48 4.1312082
04/09/2014 11:04:35 2.674
04/09/2014 11:04:39 5.649
04/09/2014 11:04:57 3.639
04/09/2014 11:05:14 2.416
04/09/2014 11:05:18 3.218

I want to show the data in a line graph with the Y axis being the last column (eg 2.687, this value is seconds), and the X axis being time (middle column). The line on the chart would represent the value of the last column by each hour and as it is over two days there would be two lines on the chart. I would be happy showing the X axis in 1 hour intervals although the actual times are hh:mm:ss. I should also add that this is just a sample of the data, there would be in excess of 10,000 entries per day. I'm trying to map out where the last column peaks and troughs throughout the day.

Hope this makes some sort of sense!![TABLE="width: 218"]
