Does anyone know how to add a hatch pattern to a bokeh plot rectangle?

from bokeh.plotting import figure, show

p = figure(width=400, height=400)
p.quad(top=[2, 3, 4], bottom=[1, 2, 3], left=[1, 2, 3],

right=[1.2, 2.5, 3.7], color="#B3DE69",
       HATCH=???
)

show(p)

I am looking for something like http://matplotlib.org/examples/pylab_examples/hatch_demo.html

Thanks,
Jeremy

Jeremy,

There is currently no support for hatching in Bokeh. There is a low-level HTML canvas for defining fill patterns, but it is not exposed. Perhaps it could be added some day, so I'd encourage you to file a GH issue for this feature request.

In the mean time, the only immediate avenue I can suggest is a custom extension that subclasses the Rect renderer and adds in a fixed pattern manually.

I won't say it is a trivial task, but if you have some familiarity with javascript/coffeescript it could bd doable. Here is the users guide section on extending bokeh:

  http://bokeh.pydata.org/en/latest/docs/user_guide/extensions.html

And here is a Stack Overflow question with information about drawing fill patterns on HTML canvas:

  http://stackoverflow.com/questions/17518107/creating-html5-canvas-patterns-and-filling-stuff-with-them

Of course, I would try to answer any specific questions as best I could if you do try this route.

Thanks,

Bryan
