Display screen or portion thereof with transitional graphical user interface

Abstract

Description

FIG. 1 is a front view of a display screen or portion thereof with transitional graphical user interface showing our new design;

FIG. 2 is a second image thereof;

FIG. 3 is a third image thereof;

FIG. 4 is a fourth image thereof;

FIG. 5 is a fifth image thereof;

FIG. 6 is a sixth image thereof; and,

FIG. 7 is a seventh image thereof.

The outermost broken lines illustrate a display screen or portion thereof and form no part of the claimed design. The remaining broken lines, including the small tick marks surrounding the inside perimeter of the clock face, illustrate portions of the graphical user interface that form no part of the claimed design.

The appearance of the transitional graphical user interface sequentially transitions between the images shown in FIGS. 1-7. The process or period in which one image transitions to another forms no part of the claimed design.

Claims

We claim the ornamental design for a display screen or portion thereof with transitional graphical user interface, as shown and described.
