I saw both versions ("in figure" and "on figure"), however---what is more correct? And is there any difference?
EDIT: In scientific papers, standards and other publications, "figures" can be found. They are also denoted as "pictures" sometimes (informally). When someone wants to refer to a part of a figure, he or she can write either "in figure" or "on figure". I am interested in figuring out if there is any difference in these two cases.
