small y-axis values for Histogram

Community Support
1

putting the following into an ipython notebook:
import bokeh.charts as bc

import bokeh

from collections import OrderedDict

#import pandas as pd

bokeh.load_notebook()

somelist = [100,100,200,200,300,300,400,400,400,400,500,600,600,600,700]

num_content = OrderedDict(billy=somelist)

hist = bc.Histogram(num_content, bins=2, notebook=True)

hist.title(“some_test”).width(400).height(350).legend(True).show()

So the y-axis shows values like:

1.500e-3

1.000e-3

Is there a reason for the y-axis numbers being so small? (0.00135)

Shouldn’t the y-axis not be something like:

8

7

6

Since I have designated 2 bins, and there are 6 values less than 100 and 9 values >= 400 Or is this not counting up the frequency of the values in the buckets?

I am looking at:

https://github.com/bokeh/bokeh/blob/d4fbe8f9a3eb647b60d6ee8ddca946f9342f1531/bokeh/charts/histogram.py

to try and understand what is going on.

Jared,

I apologize, this got lost in the shuffle. This does seem like a bug, I have created a GH issue here for it:

  Odd Histogram behaviour · Issue #1507 · bokeh/bokeh · GitHub

Thanks,

Bryan

This is actually not a bug… I will answer in the 1507 issue to avoid duplication.
