Bokeh automatic shading

I understand that this may not be possible, but does anyone know if it is possible to turn off the “automatic shading” that occurs on charts when looking a lots of data from a high level of zoom? For example at a high level of zoom I see something like this:

Does anyone know if it is possible to keep the tails from blurring at a high level? Ideally I would like them to either appear with one pixel of width, or not be shown at all.

Thanks,

Matt
