gnuplot

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

问题 This question is related to gnuplot histogram: How to put values on top of bars. I have a datafile file.dat : x y1 y2 1 2 3 2 3 4 3 4 5 and the gnuplot: set style data histogram; set style histogram rowstacked; plot newhistogram 'foo', 'file.dat' u 2:xtic(1) t col, '' u 3 t col; Now I want to place the sums of columns 2 and 3 above the bars. The obvious solution plot newhistogram 'foo', 'file.dat' u 2:xtic(1) t col, '' u 3 t col, \ '' u ($0-1):($2+$3+0.2):($2+$3) notitle w labels font "Arial

问题 In gnuplot, I type gnuplot> set style data lines Then I run few other lines: gnuplot> plot "./data/traj1.dat" u 1:4, "" u 1:6, "" u 1:9, "" u 1:11, "" u 1:13, "" u 1:15 gnuplot> plot "./data/traj2.dat" u 1:4, "" u 1:6, "" u 1:9, "" u 1:11, "" u 1:13, "" u 1:15 gnuplot> plot "./data/traj3.dat" u 1:4, "" u 1:6, "" u 1:9, "" u 1:11, "" u 1:13, "" u 1:15 Now I want to change style.

问题 Assume that I have some array of data (a vector to be specific). Can I plot it element by element sequentially using Gnuplot such that it seems as if it is a real life signal that is being traced through a monitor? I know that I can write the whole data into a text file using Common Lisp, then using gnuplot I can plot it in a batch format. What I require is that I want to put a point on my plot as data comes sequentially. Data will probably be generated inside a loop, thus you may consider x

问题 I have a layout of 3,1 plots using multiplot. All of the three plots have the same scales, so I just want to show one colorbox, on the right margin. However, once I unset the colorbox for the first two plot, the size of the three plot are different. Can anybody tell me how to implement this with the three plots have the same size? 回答1: You must set a fixed right margin with e.g. set rmargin at screen 0.85 . That sets the right border of the plot at 85% of the image size: set multiplot layout

问题 Can the following be done in gnuplot? If yes, how? I have data for time vs position(x,y,z) in a table with t,x,y,z as headers. I would like to know if I can somehow plot the same time vs position of the particle inside a predefined space with a pause after each time step; so that i can see the evolution of the particles position with time. I would also like to know if I can draw a continuous line from the previous position to the current position so that I can actually see the track of its
