I input a data set with 4 columns total. I am trying to generate an x,y graph that will keep the y axis constant from column 1 and graph columns 2,3,and 4 on the x-axis. They would need to be labeled seperately because they vary greatly from one another. How do I do this?
Study the help page for the Part function
https://reference.wolfram.com/mathematica/ref/Part.html
including the information that is hiding behind “Details.”
Then you might study the help page for the PlotStyle option
https://reference.wolfram.com/mathematica/ref/PlotStyle.html
and see if those give you some ideas.
