O článku:
The class of real functions with connected $G_delta$ graph
has some nice properties. For example, it is known that
Sharkovski?ui?'s ordering of periods holds in this family of
functions. We modify the example of function constructed by
[J.~Jastrz{og{e}}bski: {it An answer to a
question of R. G.~Gibson and F.~Roush}, Real Anal. Exchange
{f{15}} (1989--1990), 340--341]
to show that there are connected $G_delta$ functions of
arbitrary high Borel class.
