问题 I have a csv file which contains 500 rows and 100 columns. I want to plot the data in the way that: Each row represent a curve on the graph. Every column represents a value on the curve (100 values). 500 such curves on the graph. The code: set xrange [0:100] set yrange [0:20] set term png set output 'output.png' set datafile separator ',' plot 'myplot.csv' But this does not seem to work. How can I configue gnuplot to achieve that? Edit: The data is in this format (Shortened): 7.898632397,7

问题 I try to plot two horizontal lines in a coordinate system using GNUPlot. The two lines represent average values in two datasets. Each dataset has the following constants: max , min and average . The same logic is to be applied to both datasets, so we can simply focus at one of them. The output should be a 800 x 800 PNG image. They share the X axis, but their Y axis is different from each other in terms of the ranges' values and unit of measurement. Naturally, the numerical values of the two

问题 I'm trying to figure out how to do fence plots in gnuplot, but I'm having a hard time understanding what's going on in the examples I find on the internet. I have a (varying) number of data sets from different points in time in my simulation, in a datafile organized as a matrix of values 1 : t1 x11 y11 // indices here indicate that (x1,y1) are a data point which t1 x21 y21 // I'd plot on a regular 2D plot for this timestep, with the ... // additional index noting which time step the values

问题 I have a script which takes data (formatted in 3 columns x,y,z ) and gives a heat map: set logscale x 10 set yrange [1e-9:2e-8] set xlabel "x" set ylabel "y" set multiplot plot 'filetest.dat' u 1:2:9 with image This is a 2D heat map, shown below: All I want to do is add contours to this plot, at some z values such as -20 to -8 in in intervals of 2. Unfortunately, none of the answers I've found have been able to help me with this. Any help would be greatly appreciated. 回答1: Although there are

问题 I am trying to plot a vector field in Gnuplot superimposing dgrid3d, pm3d and vectors. I can get dgrid3d and pm3d to work but when I try to superimpose the vectors weird things happen. I am trying the following: set dgrid3d 50,50,2 set pm3d at b set hidden3d splot 'v-field.dat' u 1:2:6 w l, "" u 1:2:3:4:5:6 w vectors Data is in the format: 0.0000000020000000 0.0833272880000000 0 0 0 1.62609277247135e-09 0.5000000020000001 0.5833272880000000 0 0 0 0.965930741599645 0.8749688835000000 0

问题 Is there a way to show the hypertext label with monospace? I would like to align some text and numbers in a hypertext label in a table like manner. But I couldn't get a monospace font as the hypertext labels. If I add font "Monospace,10" I'll get an error message ... unexpected or unrecognized token . Trying to use "\t" in the label was also not successful. I am using Win7/64, wxt-terminal, gnuplot 5.2.6. Any ideas? My code: ### hypertext with monospace? reset session set title "Hypertext

问题 Hi to whole stackoverflow group, I am having a series of problems when defining the axes range in my graphic and format in general, and I would like to share it with you to see if among all we can find the error I have found on this website a user who has made it similar. My idea is to have something similar like the graphic of the link below. But for some reason, it's probably silly, it does not appear correctly. My code is as following: set term post eps enhanced color "Times-Roman" 14 set

问题 I have a data file test.tsv which consists of three columns: letter start end a 15 20 a 40 60 b 124 171 b 237 316 I set y axis to represent the a and b, How can I get lines cover start to end? 回答1: In a more general case you could do the following which is similar to the solution here. Create a list of unique keys and use those as the y-axis tics/labels. Define a lookup function and plot the data accordingly. You can use the plotting style with vectors but if you want thicker bars instead of

问题 I have three data files each with a matrix; I use stats to find the maximum value in the matrix for each file and it is displayed correctly. I need to use those three maximum values as data points and plot them so as to have points on my plot as (1.0, A_max), (2.0, B_max) and (3.0, C_max) where A_max is the maximum value calculated using stats from first data file, B_max from second and C_max from third. Here is how my gp file looks like : set terminal epslatex size 3.5,2.62 color colortext
