Position the legend outside the plot area with Bokeh

I am making a plot following the example found here

Unfortunately, I have 17 curves I need to display, and the legend overlaps them. I know I can create a legend object that can be displayed outside the plot area like here, but I have 17 curves so using a loop is much more convenient.

Do you know how to combine both methods?

Answer

Ok, I found the solution. See the code below where I have just modified the interactive legend example:

import pandas as pd
from bokeh.palettes import Spectral4
from bokeh.plotting import figure, output_file, show
from bokeh.sampledata.stocks import AAPL, IBM, MSFT, GOOG
from bokeh.models import Legend
from bokeh.io import output_notebook

output_notebook()

p = figure(plot_width=800, plot_height=250, x_axis_type="datetime", toolbar_location='above')
p.title.text = 'Click on legend entries to mute the corresponding lines'

legend_it = []

for data, name, color in zip([AAPL, IBM, MSFT, GOOG], ["AAPL", "IBM", "MSFT", "GOOG"], Spectral4):
    df = pd.DataFrame(data)
    df['date'] = pd.to_datetime(df['date'])
    c = p.line(df['date'], df['close'], line_width=2, color=color, alpha=0.8,
           muted_color=color, muted_alpha=0.2)
    legend_it.append((name, [c]))


legend = Legend(items=legend_it)
legend.click_policy="mute"

p.add_layout(legend, 'right')

show(p)
