not a correct time display in gnuplot -

i started gnuplot , have problem using "time" x-variable. have tried lot of things cannot right. data looks like

#  10-05-2013 1-52-56, 425,"lvl"   10-05-2013 1-52-57, 425,"lvl"   10-05-2013 1-52-58, 433,"lvl"   10-05-2013 1-52-59, 433,"lvl"   

i want plot values (425 etc) y , date/time x (this date/time example uses date starting 1 (e.g. 1 am) instead of 01 same problem occurs time e.g. 19 hours). 1-52-56 means 1 hour, 52 minutes , 56 seconds.

this part of script use (the dataset build "on fly"):

i incoprorated entire code because perhaps wrote on beforehand messes graph, assume problem lies within:

set xdata time set timefmt "%d-%m-%y %h-%m-%s" 

the plot uses labels incorporate minutes , seconds, not hours or date. can not right. please @ , tell me waht doing wrong?

thanks!

the plot uses labels incorporate minutes , seconds, not hours or date.

the format of xtic labels can changed set format x '<format>', e.g. include date , hours use:

set format x '%d/%m - %h:%m:%s' 

these quite long , perhaps want better room them:

set xtics rotate -45 

see help time/date more.
