Cells are the elements of the graph model. They represent the state of the groups, vertices and edges in a graph.
Edge Labels
Using the x- and y-coordinates of a cell's geometry it is possible to position the label on edges on a specific location on the actual edge shape as it appears on the screen. The x-coordinate of an edge's geometry is used to describe the distance from the center of the edge from -1 to 1 with 0 being the center of the edge and the default value. The y-coordinate of an edge's geometry is used to describe the absolute, orthogonal distance in pixels from that point. In addition, the mxGeometry.offset is used as a absolute offset vector from the resulting point. The width and height of an edge geometry are ignored. To add more than one edge label, add a child vertex with a relative geometry. The x- and y-coordinates of that geometry will have the same semantiv as the above for edge labels.
