#Gnuplot for loop portable
Set title strsubst(GRAPH_NAME, "_", " \\ _") Gnuplot is a portable command-line driven graphing utility for Linux, OS/2, MS Windows, OSX, VMS, and many other platforms. which means 'plot the file using column 2 as X and column 4 as Y'. Assuming you have N files named sequently, i.e. To specify the columns to be plotted use the using specifier. The simplest method to plot multiple data files is to insert a for loop inside the plot command of gnuplot. Specify the x range first, then the y range. You can specify these in a minimum:maximum form before the function. The default settings will use the first two columns of your data file, respectively x and y. So, after starting up gnuplot, at the gnuplot> prompt you would type: plot exp (-x2 / 2) Usually, you'll want a little more control over your plot, at least specifying the ranges for the x- and y-axes. Set output sprintf( '%s/%s.png',OUTPUT_DIREC_PATH,GRAPH_NAME) gnuplot will produce a graph in your output destination. OUTPUT_DIREC_PATH = "C:/Users/norun/Desktop" cd INPUT_DATA_DIREC INPUT_DATA_DIREC = "C:/Users/norun/Desktop/gnu/format" #set xtics 200 #set ytics 200 #load 'C:\Users\norun\Desktop\gnu\pre\config_y2_letter_style.txt' #set y2label "y2-label" rotate by 270 #set y2range #set y2tics 100 # 出力設定とサイズ # set size ratio 1 1 set terminal png size 1920, 1920 # 結果出力、プロット #
This is necessary while running in non-interactive mode from the command line, otherwise the image disappears after execution. p -> Keep the window open after the GNUPlot command exits. … do for コード load 'C:\Users\norun\Desktop\gnu\pre\subst_underline.txt' load 'C:\Users\norun\Desktop\gnu\pre\config_letter_style.txt' load 'C:\Users\norun\Desktop\gnu\pre\set_style_line_1.txt' # 軸、凡例設定 # set key left top set key reverse #set key invert #set key spacing 0.7 #set grid set xlabel "x-label" set ylabel "y-label" set xrange Generate a basic graph with GNUPlot: gnuplot -p -e 'set format y '.0f' plot for col1:3 '/tmp/numbers.txt' using col with lines'. Gnuplot has been supported and under active development since 1986. It is also used as a plotting engine by third-party applications like Octave. Sepal.Length,Sepal.Width,Petal.Length,Petal.Width,Species It was originally created to allow scientists and students to visualize mathematical functions and data interactively, but has grown to support many non-interactive uses such as web scripting. 例によって、下記の様なirisデー タセットのサンプルを用いる。 # iris.dat Version 4.6 of gnuplot introduced command iteration and block-structured if/else/while/do constructs. The -p flag just allows the plot to persist beyond the command call (otherwise it disappears) and -e tells gnuplot to expect the following script, which is surrounded by quotes.
dat, whatever your data is saved as) to filter out unwanted files.Įxample: Plot all. This basically feeds the script from above into the gnuplot command-line call. I'll try to think more about this when I have time, but it would be great if you could add some examples to the tests/indentation.gnuplot file. I don't use this feature of gnuplot, though, so it's hard for me to tell whether this code works. In case you have a lot of data files so that manually renaming them to follow a formula is not realistic, you can check the file format (.txt. thanks for pointing this out I created a new 'loop-indentation' branch and added a quick solution. Weijun Zhou already presented you with a working albeit slightly volatile solution.
