问题 I'm struggling to get a multi-column bar chart / histogram going with my input as a CSV with headings. As well as the key showing the {wcfiles,wclines,clocfiles,cloclines} attributes. $summary << EOD browser,wcfiles,wclines,clocfiles,cloclines webkitgtk-2.28.2,19472,4710385,18620,3120740 firefox-78.0.1,289298,43627834,240137,24371602 chromium-83.0.4103.116,420343,100340817,269434,49597826 EOD set datafile separator ',' set yrange [0:*] # start at zero, find max from the data set style fill

问题 I was trying to create something like But I was not able to get the x and y axis tics coming in I tried something like this to see if the x axis tics are coming my @data = ( [0, 0, 10], [0, 1, 10], [0, 2, 10], [], [1, 0, 10], [1, 1, 5], [1, 2, 10], [], [2, 0, 10], [2, 1, 1], [2, 2, 10], [], [3, 0, 10], [3, 1, 0], [3, 2, 10], ); my $chart = Chart::Gnuplot->new( output => "test1.png", title => "3D plot from arrays of x, y and z coordinates", xlabel => 'x', ylabel => 'y', xtics => { labels => ['

问题 Without choosing the color explicitly like Different coloured bars in gnuplot bar chart? is there a way for GNU plot to choose some distinguished colors based on the key (like a hash?)? # git rev-list --count master $commits << EOD gecko 716280 webkit 226748 blink 906439 EOD set terminal png set yrange [0:*] # start at zero, find max from the data set boxwidth 0.5 # use a fixed width for boxes unset key # turn off all titles set style fill solid # solid color boxes set title 'commits' plot '

问题 I'm trying to animate 2D vector with gnuplot. I want to show one line i.e, one vector at a time. My Data Structure is as follows: They x,y,u,v 2.24448 0.270645 1.00 1.00 3.24448 0.270645 0.500 1.20 I'm able to create a static plot sing following command: plot "datam.dat" using 1:2:3:4 with vectors filled head lw 3 Here is the output: Here is my question: I would like to animate and show one row (i.e,) one vector at a time , how to accomplish this in GNU plot using GIF? Thanks 回答1: Animated

问题 With pointinterval , it is possible to tell Gnuplot when to insert the point on the line. Now, by setting that to -1, the line doesn't go though the point. For example pi -1 ----<>----<>----<>----<>----<>----<>----<>----<>----<>---- pi 2 ----<->----------<->----------<->----------<->----------<->---- As you can see, using values other than -1 will insert the line inside the point. I want to use positive pi in order to reduce the number of visible points and at the same time I want to see that
