Grischa, The following will do it (assume that your list of y values is called ylist) ylist = {-3,-1,0,3,5,9} Plot[Evaluate[f[x,ylist]],{x,-3,3}] regards... RF >>> Grischa Stegemann <Stegemann at Physik.TU-Berlin.DE> 07/05/00 09:10PM >>> Dear group I have a two parameter function, e.g. In[1]:= f[x_,y_]:=x+y Now I would like to plot f[x,y1],f[x,y2],... within the same chart. Usually you would try something like this: In[2]:= Plot[{f[x,1],f[x,2],f[x,3]},{x,-3,3}] Since my list of y's is pretty long I tried this: In[3]:= ylist={1,2,3}; Plot[Map[f[x,#1]&,ylist],{x,-3,3}] but Mathematica complains Plot::"plnr": (f[x, #1]&)/@ylist is not a machine-size real number at x=-2.9999997 On the other hand we have In[4]:= Map[f[x,#1]&,ylist] Out[4]= {1 + x, 2 + x, 3 + x} and In[5]:= Plot[{1 + x, 2 + x, 3 + x},{x,-3,3}] of course works as expected.
