Bar chart with different patterns (print-friendly black and white)

Howdy y’all,

I’m trying to add different “patterns” inside the bars for a print-friendly black and white plot, see example. But I’m not sure if this feature can be done in Bokeh. This is also a question in stackoverflow. I’m using Python 2.7 and for coding the bar chart I’m using the method quad, as it’s used in this question.

I would thanks any helps on this…
