Basic python question

  1. Aug 13, 2013 #1
    How do if you have a .csv file with 3 columns (independent, dependent, uncertainty in dependent variable), how do you make a graph so that the independent variable is the x-axis and the dependent is the y axis?

    All I've done is
    Code (Text):
    pylab.plot(data,"ko")
    pylab.show()
    The graph I get seems to have plotted the independent variable as the dependent...as well as the other two columns

    hhhmmm...passing a single 2D array may be causing plot to plot all columns against the row index...try passing the individual columns explicitly, something like plot(data[0],data[1],'ko')

    Thanks, got it now. Looks like it's plotting everything correctly
