And let me just say that I wouldn't claim any part of the prize if someone finished that ticket. It would satisfying enough to me that we had the feature, which I've wanted for a long time! Note that there are a few things that are different about the code on the ticket and the requirements on the blog. The code on the ticket does not implement a locator control *inside* the picture. Instead, it implements a 2d locator control in a square box in the controls section of an interact (Mathematica also has something like this). I see several things needing to be done to that ticket: 1. Figure out a way to have interact input in the *output* of the interact. It seems like you'd need some way of saying "put a locator control on *this* graphic that I'm printing out right here". 2. For a locator control to be useful, it needs to return values in the data coordinates of the plot (rather than pixels in the image). I think it would be easy to return the pixel location in the image (once (1) is solved). You'd probably use the transformation framework in matplotlib to convert that to data coordinates. 3. I'm not sure how easily new controls can be easily created. That would need to also be solved in order to meet the requirements. Anyways, those are three main points that I would think need to be addressed in the implementation of such a control. However, I'd love it if someone did it some simpler way and proved me wrong! Those obstacles are what prevented me from finishing up the ticket mentioned above---I just didn't have time to put towards it (and still don't for the foreseeable future). All in all, I think having 2d interacts would not only give us a valuable control, but would prove useful in refining the existing interact infrastructure. So thanks for proposing a bounty! I'm excited to see someone win it.
