You could also execute load "test.p" from within gnuplot, after you copied test.p into the working directory. splot ((sin (sqrt(x**2 y**2))))/sqrt((x**2 y**2)) gnuplot is a freeware graph plotter app and calculator developed by gnuplot Team for Windows, its powerful, efficient and helpful.Start gnuplot (open terminal, type gnuplot) ![]() I used gnuplot4.0 under MacOSX 10.4, but there is no reason this shouldnot work on other systems.

"my_table" using 1:3 title "1vs3" with lines, \ In order to plot this kind of data the for command of Gnuplot can be used to iterate through the data. ![]() Plot "my_table" using 1:2 title "1vs2" with lines, \ Set title 'Frankia cumulative nucleotide skews' General iteration spanning multiple commands is possible using a block construct as. #set nokey #omits the legend in the right hand corner Gnuplot - Plot data points on 2D contour plot - Ask Ubuntu Gnuplot - Plot data points on 2D contour plot Ask Question Asked 4 years, 8 months ago Modified 4 years, 8 months ago Viewed 9k times 1 I want to plot some data points ( MCoordPlain.txt) onto a 2D contour projection (which is made by data on Contours.txt ). Simple iteration is possible inside plot or set commands. #set multiplot # allows multiple plots on the same page The easiest way to install it on a Mac is to use the Fink package installer ( here).ĭemo: plotting data from the file set terminal postscript landscape color 20 GnuPlot is the best plotting program I've seen so far.
