[SOLVED] [gnuplot] Ugly labels

gregors · 03-01-2020, 01:03 PM

Hi there!

Since this question has been left unanswered for a few weeks now (in de.comp.software.graphic) I'm hoping to find someone here who can tell me what I could do to have some nicer labels on the x-axis in http://test.szaktilla.de/plot.pdf

I would like to have those long dates either rotated ~30° CCW or shortened.

Do you know how to achieve that?

TIA

Gregor

The script I'm using so far:

Code:

#!/usr/bin/gnuplot

FN = "/home/gszaktilla/.stromlog/log.txt"

set terminal postscript
set output "/tmp/plot.ps"

set xlabel "Datum"
set title FN

set timefmt "%d.%m.%y"
set xdata time

set grid

set ylabel "Zaehlerstand [kWh]"
plot FN using 1:2 notitle with lines lt 1;

set ylabel "Monatl. Verbrauch [kWh]"
set yrange [0:200]
plot FN using 1:3 notitle with lines lt 1;

#eof

And the raw data:

Code:

01.04.18, 3555, 27, 27
01.05.18, 3570, 15, 42
01.06.18, 3585, 15, 57

01.12.18, 3797, 37, 308
01.01.19, 3841, 44, 352

I have a graph I generate hourly of spam blocking statistics. A line graph with a tic for each hour.
The .dem file contains

Code:

set xtics nomirror rotate 1
set xtics ("1600" -22, "1700" -21, "1800" -20, "1900" -19, "2000" -18, "2100" -17, "2200" -16, "2300" -15, "2400" -14, "0100" -13, "0200" -12, "0300" -11, "0400" -10, "0500" -9, "0600" -8, "0700" -7, "0800" -6, "0900" -5, "1000" -4, "1100
" -3, "1200" -2, "1300" -1, "1400" 0, "1500" 1, "1600" 2, "1700" 3, "1800" 4, "1900" 5, "2000" 6, "2100" 7, "2200" 8, "2300" 9, "2400" 10, "0100" 11, "0200" 12, "0300" 13, "0400" 14, "0500" 15, "0600" 16, "0700" 17, "0800" 18, "0900" 19, 
"1000" 20, "1100" 21, "1200" 22, "1300" 23, "1400" 24, "1500" 25, "1600" 26, "1700" 27, "1800" 28, "1900" 29, "2000" 30, "2100" 31, "2200" 32, "2300" 33, "2400" 34, "0100" 35, "0200" 36, "0300" 37, "0400" 38, "0500" 39, "0600" 40, "0700" 
41, "0800" 42, "0900" 43, "1000" 44, "1100" 45, "1200" 46, "1300" 47)

and those time are rotated 90 degrees.

Wrote that a long time ago. Don't recall where the documentation is, but I'd probably start at gnuplot.info to find the answer to your question.

Had to peek: On page 178 here is the syntax for set tics, including that for rotation.

Enjoy!
