Attached is a very simple version. It assumes your sample data is in a file.
The first line is "magic" and makes significant assumptions about where python is installed on your system. This may or may not be the right answer for your system. Plotting requires matplotlib which you may need to install. ------------ #!/sw/bin/python import numpy import matplotlib.pyplot as plt dataset = numpy.genfromtxt(fname='readata.txt',skip_header=1) print dataset x=dataset[:,0] y=dataset[:,1] plt.figure(1) plt.plot(x,y) plt.plot(x,y,'ro') plt.show() -------------- On Nov 1, 2011, at 9:29 , yelena wrote: > > I have numpy. > I need the body of a program, which plots y dependence of x. > > Maybe than I'll figure out how does it works... > > > Daniel Hyams wrote: >> >> One quick way of doing this is to use numpy: >> >> import numpy >> >> dataset = numpy.genfromtxt(fname='yourfilename',skip_header=1) >> >> http://docs.scipy.org/doc/numpy/reference/generated/numpy.genfromtxt.html >> >> On Tue, Nov 1, 2011 at 8:50 AM, yelena <somebo...@inbox.lv> wrote: >>> >>> Hi! >>> I'm new at Matplotlib, so I need a little help. >>> I was trying to load data from txt files with no luck. >>> I have 2 collumns in txt files and I need to plot a XY graph.
