# Use of Normal with layers and plots

In documentation of ConstantPlusLayer we find

net = NetChain[{ ElementwiseLayer[Sin],
ConstantPlusLayer["Biases" -> {1, 3, 5}]}]
Plot[net[{x, x, x}] // Normal, {x, -10, 10}]


What is the point of using Normal? The plot works perfectly without it

• as an aside, "ConstantPlusLayer" is apparently not recognized by the stackexchange parser – magma Apr 24 at 14:10
• Likely just a documentation error, but not a bad one since it is just an unnecessary addition. – user6014 Apr 24 at 14:21
