Updated: Now includes handling the data sample and uses mpl dates functionality. import matplotlib.pyplot as plt from matplotlib.dates import DateFormatter, MinuteLocator, SecondLocator import numpy as np from StringIO import StringIO import datetime as dt ### The example data a=StringIO(“””a 10:15:22 10:15:30 OK b 10:15:23 10:15:28 OK c 10:16:00 10:17:10 FAILED b 10:16:30 10:16:50 OK “””) … Read more
With octave 3.8.2 it is working fine. x=1:10; plot(x, x, “linewidth”, 5) set(gca, “linewidth”, 4, “fontsize”, 12) yields as it should
Gnuplot can read column names from the first line, but you can still specify the column names normally as well. Therefore, this effectively skips the first line. Issue the command set key autotitle columnhead This tells gnuplot that the first line is not data, but is the column names to be used for the key. … Read more
Actually, set size ratio -1 set the same ratio in all direction independently of the window while set size square plot in a square box, no matter what range you use.
You can have the axes handled automatically without you having to scale them yourself and keep auto-scaling: set terminal jpeg set output ‘graph.jpg’ set xrange [-10:10] set ytics 10 nomirror tc lt 1 set ylabel ‘2*x’ tc lt 1 set y2tics 20 nomirror tc lt 2 set y2label ‘4*x’ tc lt 2 plot 2*x linetype … Read more
I had the same question this year (2021), and it looks like there’s support for it now. In short, you just have to double-click on the empty legend item for the series, and it’ll give you a place to put text, directly in the chart. Here’s what my chart looked like (with no series titles): … Read more
It appears that the “every” command in gnuplot is what you’re looking for: plot “filename.txt” every ::1000::2000 using 1:2 with lines Alternatively, pre-process your file to select the rows in which you are interested. For example, using awk: awk “NR>=1000 && NR<=2000″ filename.txt > processed.txt Then use the resulting “processed.txt” in your existing gnuplot command/script.
setenv(“GNUTERM”,”qt”) in your octave command prompt, it should solve the problem.
The problem is likely to be the graphics toolkit which your installation of Octave is using. To check this, type graphics_toolkit in the Octave command line. If the response is fltk and your plot window is freezing, then switch the default toolkit to gnuplot: graphics_toolkit(‘gnuplot’) Test that the problem is fixed: x=1:10; y=x.^2; plot(x,y) Make … Read more
As far as I see, the problem is (as you already wrote), that MeanResidualLife takes a long time to compute, even for a single evaluation. Now, the FindMinimum or similar functions try to find a minimum to the function. Finding a minimum requires either to set the first derivative of the function zero and solve … Read more
