[pstricks] PSTricks Coordinates by Point and Click

So after some additional searching I found a solution which seems to work reasonably well for Mac users, so I will share it here. The tools involved are: 1) your favorite latex editor + your favorite pdf viewer 2) GraphClick, and 3) Afloat. Graphclick is used to calibrate the coordinate system and grab the pstricks-coordinates. Afloat is used to make the Graphclick window transparent so that you can actually see the PSTricks figure in the pdf viewer underneath. Works very well for me. 

Thanks for your comments.

What I am searching for is a tiny bit of WYSIWYG for my PSTricks-Workflow. In particular, I am annotating a lot of graphs, which I get from another program. At the moment, I determine the exact position of my annotations by an iterative procedure: activate pstricks grid -> put label at (x,y) -> compile -> not exactly where I wanted -> change coordinate -> etc. - If one has 20 annotations, this can take a long time and it would be much easier to just click at the correct position in the pdf and get the PSTricks coordinate like (6.31, 2.11) in the clipboard. Via google I found a lot of tools that can digitalize graphs, i.e. grab data points from pictures, such as jpg, pdf, and so on, by first setting up a reference frame and then point and click.!
