That's right. There isn't a way to draw from a fixed point on the screen to an atom. You might try a recent addition in relation to PyMOL. This is a much more general offset method that is used in PyMOL and I needed to implement in Jmol, so we have it as well now. Do give this a try and let me know if it solves your problem: new feature: PyMOL-like label offset options: set labelOffset [sx, sy, sz] set labelOffset [mode, sx, sy, sz, ax, ay, az] where sx,sy,sz are screen coord offsets -- in Angstroms -- applied after view rotation -- sy > 0 LOWERS label ax,ay,az are xyz position (in Angstroms; applied before view rotation) mode == 1 indicates xyz position is an offset to the atom position mode != 1 indicates xyz position is absolute defaults: mode == 1; ax = ay = az = 0 Note that those sx sy sz are not in pixels, they are in angstroms. Also, I note that there is a bug that disallows label pointers with this sort of offset. Hmm.... On Sat, Jun 29, 2013 at 1:50 PM, James <ja...@ry...> wrote: > Thanks Angel.
