gnuplot: data from url
问题 What is the best way to plot data from an url? Currently, I have pl "<wget -q -O - http://skuld.bmsc.washington.edu/scatter/data/Ta.dat" us 1:2 The option -q (quiet) suppresses download information and -O - redirects to stdout. This relies on wget on Linux. But I think, I have seen somewhere an even easier way. 来源： https://stackoverflow.com/questions/62300543/gnuplot-data-from-url

Using gnuplot to create data files
问题 Hey guys I am currently working with gnuplot. I have this .csv file which I have been using to plot some formulas (eg plot "filename.csv" u 0:day($0) = $0 ). The plots worked out; however, I was wondering if there was a way within gnuplot to save the output of my formulas as a data file too. 回答1: Please check the manual or in the gnuplot console type help table . Code: ### save data as text reset session f(x) = x g(x) = x**2 h(x) = x**3 set xrange[-5:5] set samples 11 plot f(x) w lp, g(x) w
