Under Linux 64bit I can use the 'graph' unit and find declaration finds 
$fpc/packages/graph/src/unix/graph.pp
Then FD on the {$i graphh.inc} gets me to
$fpc/packages/graph/src/inc/graphh.inc

Works on 2.6.4 and 2.7.1.

It works with unit ptcgraph as well:
$fpc/packages/graph/src/ptcgraph/ptcgraph.pp
$fpc/packages/graph/src/inc/graphh.inc

Have you tried Tools / Rescan FPC source directory?

Note: The FPC source directory has its own search paths. It does not use
the project's search paths.
