I am not sure why you - format x %td_HH:MM:SS- while I formatted - format x
%tc_HH:MM:SS-. What happens when you
***
format x %9.0g
l in 1/5

Subject: Re: AW: st: RE: Graphing time on the x axis
To me there doesnt seem to be any difference between the sets, but doing the
following explains why the graph looks as it does. However I do not
understand how this comes about or how I can rectify it...
. list x in 1/5
+----------+
| x |
|----------|
1. | 00:00:00 |
2. | 00:00:18 |
3. | 00:00:30 |
4. | 00:00:36 |
5. | 00:01:06 |
+----------+
. sort x
. list x in 1/5
+----------+
| x |
|----------|
1. | 05:10:24 |
2. | 05:10:30 |
3. | 05:10:36 |
4. | 05:10:42 |
5. | 05:10:48 |
+----------+
