Different Plot Filling for multiple curves

Question

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?

Answer 1

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}]
