Warning: possibly dumb question :-(

I have two functions I want to plot with the Filling option, like:

Plot[{Sin[t], Cos[t]}, {t, 0, 4 Pi}, Filling -> Axis]

That's OK. But if I only want the sine filled, and try

Plot[{Sin[t], Cos[t]}, {t, 0, 4 Pi}, Filling -> {Axis, None}]

MMA returns error messages that Axis and None are not valid Filling specifications. How can I selectively apply Filling?

Remember to look in the documentation when facing problems like this. Most options are well documented. For this case you could go to Filling and see that it states:

{i1->p1,i2->p2,...} fill from object ik to pk

So for your case you would write:

 Plot[{Sin[t], Cos[t]}, {t, 0, 4 Pi}, Filling -> {1 -> Axis}]

  • $\begingroup$ Thanks, jVincent. Easier than I anticipated. @J.M. - I had looked in the documentation, but stumbled over the fifth bullet item. Probably expected something more sophisticated. $\endgroup$ – stevenvh Aug 16 '12 at 8:48
