This study deals with a construction of the canonical formalism for fields associated with the unit-disk medium which is a continuous version of a planar Feynman graph. The variable which plays the role of the "time" is defined with the help of a conjugate field which is holomorphic in the domain outside the unit disk. Commutation relations for Taylor coefficients are obtained by means of canonical quantization. Equations of "motion", which are compatible with those derived by group-theoretical consideration, are consistently presented. Finally it is suggested that a quark line should always make a loop on a Riemann sphere if the new field holomorphic outside the unit disk is an analytic continuation of the original field which is holomorphic inside the unit disk.
