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 a first image in a first sequence according to the claimed design; and,

FIG. 2 is a front view showing a second image thereof; and,

FIG. 3 is a front view showing a third image thereof.

The appearance of the transitional image sequentially transitions between the images shown in FIGS. 1-3. The process or period in which one image transitions to another image forms no part of the claimed design.

The longer outer-most broken lines showing an electronic device illustrate environmental subject matter. The regular broken lines showing a display screen and elements of the graphical user interface illustrate portions of the article. None of the aforementioned broken line subject matter forms part of the claimed design.

The heavy broken lines shown as rows of horizontal rectangles form no part of the claimed design. The narrow double lines, including a broken line segment at the left end of the lower line, do form part of the claimed design.

Claims

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