[Gnuplot-info] Need help: Time/date format

[steffen <kla...@on...>]

Hi,
I'm going to generate a plot of sunrise time versus date. 
The data file looks like

2010-12-02 7:53
2010-12-03 7:55
2010-12-06 7:59
2010-12-07 8:00
...

So, in the first column is the date (shall be x-axis), in the second the time
(y-axis). To read the date correctly I did:

set xdata time
set timefmt "%Y-%m-%d"

But the time (y-axis) is not read correctly, just integer hours. How to set up
the format (time) for the y-axis?

Thanks for help.
