Mathematica allows you to set the option defaults to meet your needs. Just SetOptions once per session and be done with it: In[1]:= Options[DiscretePlot, {Filling, Joined}] Out[1]= {Filling -> Axis, Joined -> Automatic} In[2]:= SetOptions[DiscretePlot, Filling -> None, Joined -> False]; In[3]:= Options[DiscretePlot, {Filling, Joined}] Out[3]= {Filling -> None, Joined -> False} Q.E.D
