You would like to make some hoppings invisible in a plot generated by kwant.plot? The following could work: the hop_color argument of kwant.plot can be a Python function. In that case the function will be called for each hopping with the two sites that are connected and is expected to return a matplotlib color description. I guess that matplotlib supports transparency, so that it should be possible to make some hoppings transparent. Alternatively some lines could be given zero width using the hop_lw argument. But actually, when plotting LDOS or something similar, I would rather use kwant.plotter.map or kwant.plotter.density. The image will be nicer, more compact, and no hoppings will be visible. Christoph
