This paper aims to rectify the recent fixed point results on graphical rectangular bmetric
spaces due to Mudasir Younis et al. (J. Fixed Point Theory Appl., doi:10.1007/s11784-
019-0673-3, 2019). Moreover, we also give the answer of some open problem in the mentioned
research related to the Kannan contraction mapping in the space described above with
its fixed point theorems
