问题 How do you make an horizontal box-and-whiskers plot in gnuplot? Similarly to this one: Gnuplot can easily be used to produce vertical box-and-whiskers plots with the 'candlesticks' and 'whiskerbars' keywords, but I have not managed to find any example of an horizontal candlesticks/box-and-whiskers horizontal plot produced via gnuplot online.

问题 I'm trying to get a linespoints plot with the points being hypertext. So far, I've managed to get linespoints working but without hypertext and I've split it into two plots overlaid, one with lines one with hypertext points. While the second "works", it results in an extra key for the points. Ideally, I want linespoints key entries for each line and points combination, not a line key and a points key. 回答1: That may be possible with a bit cheating. Usually the hypertext is shown only if also

问题 Is there maybe a way to draw a filled area with a hole in it? A practical example would be to draw the borders of South-Africa with transparent background. A simple copy&paste example below. Plotting index 0 and index 1 separately or plotting in background color does not help. Any ideas? Code: ### filled area with hole reset session # set term wxt size 600,400 set term pngcairo size 600,400 transparent set output "FilledWithHole.png" $Data <<EOD 2 2 8 2 8 8 2 8 2 2 4 4 4 6 6 6 6 4 4 4 EOD

问题 I need to do this in gnuplot: plot 1:4 where col 2=="P1", col 3=="3", col 1 has substring "blur1" Heres a dataset: col_1 col_2 col_3 col_4 gcc.blur1.O0 P1 3 10.5 icc.blur1.O2 P2 5 9.8 gcc.blur2.O3 P2 3 8.9 Thanks in advance. 回答1: AFAIK you need to use an external script to check for substrings. Something like awk and use plot "< awk '{...awk commands...}' input.dat" If you just want to test col_2 for P1 you can do it in gnuplot via f(x,y)= (x eq "P1"? y : 1/0) plot "input.dat" u 3:(f(strcol(2

问题 Some what related to previous question I would like to take the default (pm3d default) colour palette of gnuplot and place a white value at X and have anything >=X as white but the rest(<X) still evently distributed with the default value. Say for example I have values between 0 and 100. I am only interested in values 0 to 30 so I do the following: set cbrange [0:30] Now values are evenly distributed between 0 and 30 with the default colour palette, however values 30.001 to 100 are all yellow

问题 I just have a little problem concerning gnuplot: I have a huge data file, containing several blocks of data and i just want to plot the data contained in the first line of each block. Thus, i use the every command: plot "../path/to/data.dat" u 1:2 every ::1::1 The Problem now is, that i want to use "with lines", but gnuplot doesn't join the plotted data with lines. There are two solutions I can think of: The first would be setting the terminal type to "table", and then plotting this new table

问题 in gnuplot, when you try to fill an area under a curve, the tics of both axes are hinded behind the solid area. Is there any way to give them to the front? I am using postcript terminal, where no transparent features are allowed (i guess) Thanks 回答1: There sure is! Before plotting, run this interactively or in a script: set tics front Try help tics interactively for more info. 回答2: After trying many options I realized that the following works properly: set tics front It seems important to

问题 I have yaxis from 0 to 100. I want a grid line after every 10 units. How can I do that? That is, how can I draw grid lines after each 10 units? 回答1: Have a look at "help grid", you probably want to do something like set yrange [0:100] set xrange [0:10] set grid ytics mytics # draw lines for each ytics and mytics set mytics 2 # set the spacing for the mytics set grid # enable the grid plot sin(x)*100 回答2: The ytics variable controls how often or sparse the y scale values will be printed and

问题 I have made the following script to draw a diagram in gnuplot. There are a few number of points each enclosed within a certain area. I want to give each enclosed region a certain color. My script is as follows: set terminal wxt set yrange [0:100] set xrange [0:100] unset colorbox set style arrow 1 nohead lc rgb 'black' set style arrow 2 nohead lc rgb 'red' set label 7 "" at 35,80 point pointtype 5 lc rgb 'black' set label 8 "" at 40,30 point pointtype 5 lc rgb 'black' set arrow from 77.0522

问题 I am new to gnuplot and do not know how to store a variable at the start of gnufile and then use it in rest partof the gnuscript. The maximum of x-range is equal to the last row in forth column of a file and it varies in every new excersize. On terminal I can print the maximum xrange by tail -n 1 data.dat | awk '{print $4}' which is giving a number say it is 3.83352. I tried with the code MAX_XTICK="`tail -n 1 data.dat | awk '{print $4}'`" and then tried to use it in xrange as set xrange [ 0
