Cannot plot Histogram on Ubuntu 14.04

I'm using Python 2.7 and Bokeh 0.12.4 on Ubuntu 14.04. I have a data frame like so:

         msrp  price
compact   1.0    1.0
sedan     2.0    3.0
suv       3.0    5.0
sport     4.0    7.0

made this way:

import pandas as pd
from bokeh.charts import Histogram, output_file, show

s = pd.Series([1,2,3,4], index=['compact', 'sedan', 'suv', 'sport'], dtype='float64')
s2 = pd.Series([1,3,5,7], index=['compact', 'sedan', 'suv', 'sport'], dtype='float64')
df = pd.DataFrame({'msrp': s, 'price': s2})

output_file('test.html')
p = Histogram(df['msrp'], title='Test')
show(p)

When I run this, I get the following error:

ValueError: expected an element of either Column(Float), Column(Int), Column(String), Column(Date), Column(Datetime) or Column(Bool), got 0    2
dtype: int64

This is puzzling because when I examine the msrp series, I get:

>>> df['msrp']
compact    1.0
sedan      2.0
suv        3.0
sport      4.0
Name: msrp, dtype: float64

Note that dtype reads as a Float. what am I doing wrong? I should note that all other chart types work properly.

UPDATE The example on the docs dont work either:

from bokeh.sampledata.autompg import autompg as df
p = Histogram(df['hp'], title='Test')

Same error. Is this a known issue? If so, the docs should be updated...

UPDATE

I'm not having this problem on a Macbook. Only Ubuntu. Are there compatibility issues between Bokeh and Linux? I'm having this issue with Bokeh 0.12.4, 0.12.3, and 0.11.0.

The old bokeh.charts API, including Histogram was deprecated and subsequently removed. To create histograms with Bokeh, you should use the bokeh.plotting API. There are a variety of ways that could work, here is one complete example, created with Bokeh 0.13:

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

measured = np.random.normal(0, 0.5, 1000)
hist, edge = np.histogram(measured, density=True, bins=50)

p = figure()
p.quad(top=hist, bottom=0, left=edge[:-1], right=edge[1:], line_color="white")

show(p)
