file_html for an Histogram example

Community Support
1

Hi, I would like to find a working simple example (3 lines I guess) to get html code of a snippet by doing something like this :

import pandas as pd
from bokeh.charts import *
from bokeh.plotting import *
from bokeh.embed import autoload_static
from bokeh.resources import CDN

df = pd.DataFrame(np.random.randn(100, 4), columns=list(‘ABCD’))
name = ‘My plot’
hist = Histogram(df, bins=50)
hist.title(“Histograms”).ylabel(“Random”).legend(True).width(400).height(350)
html = file_html(******, CDN, name)

What must I put instead of ******? I tried hist, curplot, other stuff, nothing works. I don’t know how to retrieve a plot object from a chart object.
Thanks guys for this great module, definetely the most exciting stuff for stats.

Here you have an example: https://github.com/ContinuumIO/bokeh/blob/0.6.0/examples/charts/histograms.py
where you are outputting to an html file.

If you are trying to embed a chart try something like this:

from bokeh.resources import CDN

from bokeh.embed import file_html

import numpy as np

we build some distributions and load them into a dict

mu, sigma = 0, 0.5

normal = np.random.normal(mu, sigma, 1000)

lognormal = np.random.lognormal(mu, sigma, 1000)

distributions = dict(normal=normal, lognormal=lognormal)

then we create a pandas df from the dict

import pandas as pd

df = pd.DataFrame(distributions)

and finally we drop the df into out Histogram chart

from bokeh.charts import Histogram

hist = Histogram(df, bins=50, filename=“histograms.html”)

hist.title(“Histograms”).ylabel(“frequency”).legend(True).width(400).height(350).show()

html = file_html(hist.chart.plot, CDN, “my plot”)

with open(“my_embedded_chart”, “w”) as f:

f.write(html)

Hope it helps!!

Cheers.
