I’m trying to get annotated arrows on directed graph. Arrows implemented with annotations, text over arrows implemented using separate annotations with injected in the middle of arrow.
I want to have annotations which will appear on hover over arrows/edges, across all length of line. I can have hover annotation only for markers. Technically i can add transparent markers with same length/size/rotation as my arrows, but the problem that markers can be only square, not rectangles.
I would appreciate any suggestion, even dirty hacks to get text on hover over edges across whole line lenght.
