You set up your proxy artist to have properties that are linked to the properties of the plot object. When one is updated, the other gets updated as well. The automatic linking of plot objects to legend proxy artists is is one of the many benefits that would come about with the future inclusion of traitlets in matplotlib. However, I don't think you need to wait for us to get that aspect working. Since you are already creating proxy artists, I think it shouldn't be that much more effort to link their properties together with traitlets.<br><br></div><div>Unfortunately, the documentation is fairly sparse, and examples are minimal as well.
