I need to create a chart, but the values for the X axis are inconsistent.
The values are date / time based. They are based on when sample readings are taken. So typically they could look like this:

27/11/2015 16:37
28/11/2015 09:00
29/11/2015 09:19
30/11/2015 10:03
01/12/2015 08:04

How can I format / display the X axis to show the readings in correctly spaced time intervals?

Thanks in advance
