how to use mapping node with gradient

[jack27121]

for extra context, i'm trying to figure out how to recreate some basic shader stuff like in the normal render engines.
Like adding a gradient from the bottom of a mesh to the top. Normally i'd use a gradient and mapping node.
But here that is not as intuitive.

the gradient node takes in just a float. But the mapping node outputs vec3, and i can't find a way to split vec3 into different channels

The Math > Vector nodes have Combine and Separate functions.
Note that you can use the Node Add > Search... (Malt) operator for searching function names too, not just node names.

Okay! I was searching for split and break, and couldn't find it
