I have a ground water data set with multiple concentrations per sampling event, with sampling events occurring off and on, such as:
| 9/24/2003 |
| 3/19/2004 |
| 3/31/2004 |
| 4/23/2004 |
| 3/11/2005 |
| 1/30/2006 |
| 5/4/2006 |
| 9/22/2006 |
| 7/29/2008 |
| 5/28/2009 |
| 8/13/2009 |
| 11/24/2009 |
| 2/11/2010 |
| 6/27/2011 |
| 7/24/2012 |
| 8/1/2012 |
| 1/19/2015 |
| 4/20/2015 |
| 7/21/2015 |
| 10/19/2015 |
I would like to plot these points as time, rather than just points along the x-axis. Any ideas?
