Sets a distance, in pixels, to move the start arrowhead away from the position it is pointing at, for example to point at the edge of a marker independent of zoom. It can be positioned with respect to relative coordinates in the plot or with respect to the actual data coordinates of the graph. This prevents any visualization mistakes.

When adding a new shape, the relayoutData variable consists in the list of all layout shapes. # absolute and specified in the same coordinates as xref. Rather than the geometry of annotations, one is often interested in extracting the region of interest of the image delineated by the shape. You can therefore define a callback listening to relayoutData.
