This is notebook illustrates plotting of lists.

xdata={1,2,3,4,5,6,7,8,9,10};
ydata={1,4,9,16,25,36,49,64,81,100};

xydata=Table[{xdata[[i]],ydata[[i]]},{i,1,Length[xdata]}];

ListPlot[xydata,AxesLabel->{"x values (a.u.)","xdata[[2]]"}]

ListPlot[xydata,AxesLabel->{"x values (a.u.)","y values (a.u.)"},Joined->True,PlotMarkers->Automatic]
