[Chicago] Bokeh methods as arguments

[Robare, Phillip (TEKSystems)]

funcs=[p.circle, p.triangle, ... ] # (13 of them)
for i, xy in enumerate(xys):
    x, y = map(list, zip(*xy))
    color, dash = colors[i], dashes=[i]
    p.line(x, y, color=color, line_dash=dash)
    funcs[i % 13 ](x, y, line_color=color, fill_color='white')

That is, make an array of function pointers and call based on the position of the function in the array.  This will only work if you actually pass exactly the same parameters to each function.  
If you don't you might get the same idea to work using functools.partial to wrap the functions to where you do have all the same parameters.

Subject: [Chicago] Bokeh methods as arguments

Is there a way to call methods of the bokeh.plotting.Figure class by passing them as an argument?

I'm trying to write a Bokeh line chart utility that provides pre-selected data point shapes, colors, and line dash styles for a to-be-determined number of data series: a consistent, predefined style that is color-blind-friendly. I can define lists for colors and dashes...
colors = ['blue', 'red', _]
dashes = [[1,0], [2,2], _]
...and pass those values easily because they are keyword arguments, but the shapes are methods of the Figure class.

Here is the behavior I'm trying to copy:

for i, xy in enumerate(xys):
    x, y = map(list, zip(*xy))
    color, dash = colors[i], dashes=[i]
    p.line(x, y, color=color, line_dash=dash)
    if i % 13 == 0:
        p.circle(x, y, line_color=color, fill_color='white')
    elif i % 13 == 1:
        p.triangle(x, y, line_color=color, fill_color='white')
    else:
        pass  # etc.

I'd like to replace the if/elif section with something equivalent to:

    p.myCall(shape_methods[i], x, y, line_color=color, fill_color='white')

Thanks!!
