The measurements have taken place at -clock-. However trying to twoway graph with clock along the x axis resulted in the problem with changing dates and jumps on the graph. I tried to cricumvent this by subtracting clock with the first clock-value.. but as you see it leaves me with the same problem. I´m sure there is someway around this... .format x %9.0g . l x clock in 1/5 +------------------+ | x clock | |------------------| 1. | 0 18:46:46 | 2. | 18000 18:47:04 | 3. | 30000 18:47:16 | 4. | 36000 18:47:22 | 5. | 66000 18:47:52 | +------------------+ M On Mon, Dec 21, 2009 at 9:58 PM, Martin Weiss <martin.weiss1@gmx.de> wrote: > > <> > > I am not sure why you - format x %td_HH:MM:SS- while I formatted - format x > %tc_HH:MM:SS-.
