Display screen or portion thereof with transitional graphical user interface

Abstract

Description

FIG. 1 is the first image in a sequence for a display screen or portion thereof with transitional graphical user interface showing our new design according to a first embodiment;

FIG. 2 is the second image thereof;

FIG. 3 is the third image thereof;

FIG. 4 is the first image in a sequence for a display screen or portion thereof with transitional graphical user interface showing our new design according to a second embodiment;

FIG. 5 is the second image thereof; and,

FIG. 6 is the third image thereof.

The outermost broken line showing of the display screen or portion thereof in FIGS. 1 through 6 forms no part of the claimed design.

The remaining broken lines in the figures depict portions of the transitional graphical user interface which form no part of the claimed design.

The grayscale tones displayed in the drawing figures illustrate a contrast in appearance.

The appearance of the transitional graphical user interface sequentially transitions between the images shown in FIGS. 1 through 3 and FIGS. 4 through 6, respectively. 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.
