gnuplot

问题 You can position the key legend manually in most plotting programs. For example, in gnuplot it's done using set key top right . In ggplot2, it's done like this. Is there a plotting library, script, or simple algorithm that automatically positions the legend such that it overlaps the data in the plot minimally? What I mean is: Suppose I plot the line y=x . A good place for the legend in that case would be top left or bottom right. 回答1: Try this, require(Hmisc) ?largest.empty there are other

问题 OK, this is not a proper programming question, but maybe the answer will help others. I've been trying to find a suitable BibTeX entry for gnuplot , to include in a scientific publication. I just don't want to cite any guide book, but the actual software. Does anyone have an idea, or ever used that? I was hoping to find something similar to the citation() command in R . Thank you! 回答1: There is no prescribed form to cite Gnuplot so there is no command like cite() . But earlier, I have also

问题 I'm using gnuplot to plot the histogram of the following data file. data.txt ========= countries 1 domestic 1 fourth-largest 3 in 4 airline 5 and 8 destinations 3 I want to plot the histogram of word frequency(y axis) against the word(x axis). 回答1: Found this: set xtics border in scale 1,0.5 nomirror rotate by -90 offset character 0, 0, 0 plot "data.txt" using 2:xticlabels(1) with histogram 来源： https://stackoverflow.com/questions/11783202/plotting-word-frequency-histogram-using-gnuplot

问题 I have the following code, which plots 4 lines: plot for [i=1:4] \ path_to_file using 1:(column(i)) , \ I also want to plot 8 horizontal lines on this graph, the values of which come from mydata.txt. I have seen, from the answer to Gnuplot: How to load and display single numeric value from data file, that I can use the stats command to access the constant values I am interested in. I think I can access the cell (row, col) as follows: stats 'mydata.txt' every ::row::row using col nooutput

问题 This question already has an answer here : excluding a tic number in scientific format (1 answer) Closed 5 years ago . Suppose I have a script like this set terminal png enhanced set output "test.png" set ytics format "%.1t 10^{%S}" set ytics 5000 set mytics 5 set xrange [0:16000] plot x Which produces the following. I do wnat major tics as well as minor tics. However, the tic at zero looks ugly, so I would like to modify or delete it. I tried set ytics (5000,10000,15000) . This is possible,

问题 I am using the following commands to draw a simple sin(x) plot on gnuplot , with a pipe from VS2010 C++ set terminal windows set title 'Graph of velocity versus time' set xrange[0:10] plot sin (x) Problem is the window keeps closing down too quickly . I don't want to use the 'pause' command as it stop the entire code. Is there any other way to keep this window open without the pause command? Cheers 回答1: I cant try it, but have you tried setting the terminal to 'set terminal x11' set up the

问题 i using ">gnujavaplot and i not found a way to make outputs image files. I just plot in gnuplot window, i need the plot output in png file. I need something like: $ a set terminal png $ set output "filename.png" in gnujavaplot. THanks. 回答1: i just copy my actual code, withoout editing, so there is a few overhead, but i think you should get the thing. The interesting part starts at ImageTerminal png = new ImageTerminal(); and dont miss the end of the code! greetings import java.io.File; import

问题 i want to generate some plots from my data that i want to include in some documentation. I put the box outside the graph area. the problem is that for different plots the box has different sizes so also the graph area changes its size. this looks very messy in the document becasue the plots are vertical aligned. I am searching for a way to fix the size of the box to some width that is appropriate for all plots but i could not found a way to do so. the set key command has a width parameter but
