How to generate series of plots programmatically?

[Henryk Nowicki]

Hi, all!

How to generate series of plots with exactly the same numbers of finance bars on the
each plot?

What I want interactively can be achievid with something like this:

....
set xrange[0:100]
replot
set xrange[100:200]
replot
set xrange[200:300]
replot
set xrange[300:400]
replot
set xrange[400:500]

etc. to the end of datafile

Here is the gnuplot script I'm working on:

#!/usr/local/bin/gnuplot
set term pngcairo enhanced font ",8" size 1600,900
set output "main.png"
set boxwidth 0.5 relative
set grid
set style line 1 lc rgb '#3B444B' lt 1 #border
set border linestyle 1
set errorbars 2.6
set border 3
set tics nomirror
set xtics 2
set xtics rotate by -90
set ytics 500
set xrange [30:60]
plot "< paste -d, main.db fast_sma long_sma signal.db" u 0:2:3:4:5 w finance lc rgb '#3B444B' lw 1.4, \
"" u 0:13 w l lc rgb '#FF7F50' lw 1.8, \
"" u 0:14 w l lw 1.8, \
"" u 15:16 w p lt 3 lc rgb 'red'

Thank you!

Several possibilities, check "help do", and "help plot for".

The range iteration is a bit tricky with "plot for" i think, the "do
for [] {}" loop has the disadvantage that you need to have a plot
already before iterating through you data with "replot". Try
generating an empty plot beforehand, e.g. via

plot 0 lc rgb "white" notitle

if necessary.
