gnuplot

问题 I'm writing a script to generate three plots in a column (using multiplot and setting margins). They all share an x-axis, so it's only necessary to label that on the bottom plot, but they have separate y-axes. I'm using the epslatex terminal in gnuplot to generate the plots with latex labels and axes. Basically, I need the numbers on the axis to use a smaller font size than the actual axis labels. So far, I've been doing this using, reset set term epslatex standalone color solid 10 set output

问题 So if i have plotted some data in gnuplot as a boxplot (set style data gnuplot), and I have outliers having the same value, then they are plotted as dots horizontally at the same place. How can I set that horizontal distance? So for example I have the datafile data.dat 1 1 1 1 1 1 1 1 1 1 1 1 9 9 and plot it using set style data boxplot plot 'data.dat' using (1):1 set yrange [0:10] How can I set then the distance between the two points at y=9? 回答1: No, you cannot change that distance, The

问题 I'm creating Gtk::Socket in my Gtk3 (actually, gtkmm) application and trying to embed gnuplot's window into it. But it does not work: the socket remains to stay as a black rectangle, while gnuplot window appears standalone elsewhere. Meanwhile, Gtk::Plug plugs into this socket perfectly. In Gtk2 this trick with gnuplot works well too. Here is socket.cpp #include <iostream> #include <fstream> #include <gtkmm.h> #include <gtkmm/socket.h> using namespace std; void plug_added(){ cout << "A plug

问题 I need to plot on the same graph a 3D surface based on a scatter points data and a 2D image (.png), positioned in a determined location on the graph to compare the data from both. So far I managed to do both separately (plotting the image and making the surface). However, when I try to bring both together on the same script, I get an error message ("Gridding of the color Column is not implemented") which occurs due to the command that creates the surface (dgrid3d) that conflicts with the

问题 I use the following script to plot a matrix file file.dat and two points on the same plot. The problem is that my x and y axis do not overlap for the two different plots. set multiplot set pm3d map splot 'file.dat' matrix unset pm3d plot '-' w p > 20, 10 > 30, 40 > e unset multiplot 回答1: Try nonuniform matrix instead of splot and pm3d map : set multiplot set size 1,1 unset colorbox plot[0:3][0:2] '-' nonuniform matrix with image 12 0 1 2 3 0 5 4 8 9 1 6 4 7 8 2 5 6 2 4 e e set size 1,1 plot[0

问题 I want to draw yerrorbars with different colors. I am able to draw points with different colors using the following code: reset plot "-" using 1:2:3 with points linecolor variable # x y linecolor -4.0 -3.8 1 -3.0 -2.9 1 -2.0 -2.1 2 -1.0 -1.2 1 1.0 1.1 1 2.0 2.2 2 3.0 3.3 3 4.0 4.5 3 end But I am not sure how to extend this to yerrrorbars . When I try and use the following code, the errorbars are colored only with default color. How do I color the errorbars with a specific color? reset plot "-

问题 I have a gnuplot datafile that looks like this: 1 4810 582 573 587 2 99k 67k 56k 40k 3 119k 82k 68k 49k 4 119k 81k 68k 49k 5 120k 81k 65k 45k 6 121k 82k 65k 44k 7 124k 106k 97k 86k 8 128k 134k 131k 131k 9 128k 130k 131k 135k 10 129k 133k 130k 132k First column will be on the X-axis labeled as "Time", the rest are the different interrupt values with respect to time (i.e. IRQ1, IRQ2, IRQ3, IRQ4) The problem when generating a plot with this is that gnuplot does not seem to interpret the

问题 I want a graph using gnuplot with two data in mixed scheme. This is a data consisting of 3 columns: x y1 y2 1 0 1 2 0 1 3 0 1 4 0 1 5 0 1 6 0 1 7 0 1 8 0 1 9 0.1 1.2 10 0.1 1.23 What I want is that one line draws without seam. e.g. From x=1 to x=5, use y1 value, then from x=6 to x=10 use y2 value. And, all the points are connected with one single line. Does any body know how to make it with simple gnuplot command? 回答1: Prue Gnuplot soulution: plot 'sheme.dat' u 1:($1<=5?$2:$3) w l If you want

问题 I'm plotting some data and I want to use dashed grid lines. Any dashed grid line would suffice, but I prefer a "long dash, short dash, long dash" format. For example, given the following code set grid lc rgb "#000000" lt 1 dt (50, 25, 20, 25) plot x**2 I get this result But I would rather the grid lines intersection to happen always at the middle of two dashes, like this If I could make horizontal grid lines different to vertical grid lines and I could add some offset to each one, then I'd

问题 I'm trying to put as the title of a plot "P@10" using GnuPlot, using the Helvetica font. What I did was this: set encoding iso_8859_1 set title "P \100 10" The \100 comes from the octal representation of the at symbol in unicode. The final plot, however, replaces the @ with a simple space. Other symbols work as expected. I also tried the matlab script provided here, to look for the @ symbol in at least 4000 different codes, but I couldn't find it. Is this possible, even with another font?
