Display screen or portion thereof with transitional graphical user interface

Abstract

Description

FIG. 1 is a front view of the claimed design;

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

The gradient background of the graphical user interface is claimed subject matter.

The longer broken-line showing of a portion of an electronic device and the intermediate-length broken-line showing of a display screen boundary, as well as the features within the interface shown in still shorter broken-lines, are included for the purpose of illustrating environmental structure and form no 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.
