How do you set the range for ListPlot (mathematica)

Question

I have a large set (about 2050 values) of data that I would like to make a graph out of. The data is in two columns in Excel. I copied the first column and made the list x={0, 3.6, 7.1, 10.7...} and with the second column i made y={0, 0, 0, ...} (there are non-zero values but they are much further along). Then I did s=Thread[{x,y}] . and then ListPlot[s]. The graph that comes out doesn' t make much sense to me (I have attached an image of the listplot and of the excel plot) The only thing that I can think of and see is that mathematica seems to be stopping the y values at 5 for some reason. However, I dont know how to extend the range for a listplot. Does anybody have any other ideas? Thanks.

Answer 1

It looks like you may have mixed the $x$ and $y$ values. Your thread command isn't working quite as you think. The 'easy' and naive way to do this is you can take the $x$ and $y$ values and create your points with

 points={}
 Do[AppendTo[points,{x[[i]],y[i]]}],{i,1,Length[x]}]

Assuming you have the same amount of $x$ and $y$ coordinates. Then you can just DiscretePlot the set points or however you wanted to plot it. Note also, it is unnecessary that you copied and pasted the points. Mathematica can import them as points directly. See the help menu for help on that!
