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

[DavidH56 <dlh...@co...>]

Hi Thomas,

I'm getting this msg with the latest script:

gnuplot> do for [i=0:m-1] {

                                   ^

         "cycle4a.txt", line 15: invalid complex constant

Here's the script I'm using; my file is "Generation Data.txt" and I want to
plot column 17. I made minor changes to the lines preceded with "*" (I
removed comments for brevity):

reset 
set macros 

m=12 

* set timefmt "%m-%d-%Y" 

set table 

n=0 
* plot for [i=0:m-1] "Generation Data.txt" \
  * using ($0>n?n=$0:0 , $0):17 every m::i 
print n 

do for [i=0:m-1] { 
   sum=0 
  * plot "Generation Data.txt" using 0:(sum=sum+$2 , $2) every m::i 
   av=sum/n 
   x=i*(n+1) 
   set arrow i+1 from x,av to x+n,av nohead lt 1 lc rgb "black" 
} 

unset table 

mn="JanFebMarAprMayJunJulAugSepOctNovDec" 
temp="set xtics (" 
do for [i=0:m-1] { 
   if (i>0) {temp=temp.","} 
   temp=temp.sprintf("\"%s\" %d",substr(mn,3*i+1,3*i+3),n/2+i*(n+1)) 
} 
temp=temp.")" 
@temp 

# and now the final plot 
*plot for [i=0:m-1] "Generation Data.txt" \
  * using (tm_mon(timecolumn(1))+$0+i*n):17 \
   every m::i \
   with linespoints \
   lt 7 lc rgb "black"
