Re: [Gnuplot-info] Can gnuplot create cycle plots (also called month plots)?

[Thomas S. <t.s...@fz...>]

assuming that your data have the following format

...
2014-01-01 169
2014-02-01 170
2014-03-01 171
2014-04-01 172
...

and that there are no gaps in the data and that there is one value
per month in every year, the following script may serve as an example
how such a cycle plot may be produced:

reset

# number of entries per month (i.e. number of years)
n=0
# number of months
m=12

# although x-data are dates, we do the conversion into
# 'seconds since the beginning of the epoch' by our own,
# so we *don't* set xdata
#set xdata time
# but 'timefmt' we need for using 'timecolumn()'
set timefmt "%Y-%m-%d"

# dummy plot to determine the value of 'n'
set table
plot for [i=0:m-1] "datafilename" \
   using ($0>n?n=$0:0 , $0):2 every 12::i
unset table 
print n

plot for [i=0:m-1] "datafilename" \
   using (tm_mon(timecolumn(1))+$0+i*n):2 \
   every m::i \
   with linespoints
