Sorry if I misunderstood the problem but would it be something like the
following?
x=RandomReal[{0,10},{20}]; (*Generate random x*)
data=Transpose[{x,x^2}] (*The function is now y=x^2*)
intFunc=Interpolation[data];
Show[ListPlot[data],Plot[intFunc[x],{x,0,10}]]
It worked over here
Hope it helps,
Gabriel
