[Gnuplot-info] why are data values truncated to int values when using "set xdata time"

[Gautam T. <gau...@lm...>]

I plot a lot of data in which the x axis data is time. Input is "%s", meaning 
just time as floating point seconds is input. When I use

set format x "%M:%S"

i notice that in my graphs truncate the seconds value and thus the fraction of 
seconds are lost. This leads to loss of information when one is looking at the 
graph. As an example, consider data file "foo" and the attached "1.gplot"

doing

gnuplot 1.gplot -

shows the graph 1.png, but in fact I would like the fractional parts of the 
seconds to be not dropped and point should be draw in between the integral 
second values.

Any comments/hints welcome. Thanks. I have used gnuplot for a long time, but 
may be I am missing some trick here.
