When plotting with Bokeh, how do you automatically cycle through a color pallette?

Question

I want to use a loop to load and/or modify data and plot the result within the loop using Bokeh (I am familiar with Matplotlib\'s axes.color_cycle). Here is a simple exampl

Answer 1

It is probably easiest to just get the list of colors and cycle it yourself using itertools:

import numpy as np
from bokeh.plotting import figure, output_file, show

# select a palette
from bokeh.palettes import Dark2_5 as palette
# itertools handles the cycling
import itertools  

output_file('bokeh_cycle_colors.html')

p = figure(width=400, height=400)
x = np.linspace(0, 10)

# create a color iterator
colors = itertools.cycle(palette)    

for m, color in zip(range(10), colors):
    y = m * x
    p.line(x, y, legend='m = {}'.format(m), color=color)

p.legend.location='top_left'
show(p)
