Recently there was another posting related to this topic by Ben Yung
<benyung@unixg.ubc.ca>. Here was my reply to Ben:
In[1]:= data=Table[{x,Sin[x]},{x,0.,3,0.5}];
Generate two lists of errors:
In[2]:= xerror=Table[{-1,1}Random[]/3,{Length[data]}]; In[3]:=
yerror=Table[{-1,1}Random[]/3,{Length[data]}];
(I have symmetric errors generated by direct multiplication by {-1,1}.
In[4]:= <<Graphics`MultipleListPlot`
Here are the errorbars
In[5]:= errorbars= Apply[ErrorBar,Transpose[{xerror,yerror}],{1}];
Now we can write
In[6]:= MultipleListPlot[Transpose[{data,errorbars}]];
Cheers,
Paul
