That's just a warning, so you can ignore it for now. I will push a fix as soon as I can.
I believe you can avoid it by passing legend=False
to Show()
.

This is what I get with passing legend=False
(same result with legend=false)
If it helps, I had the same error on Jupyter Notebook chap02ex, but strangely enough the error went away. The error described above occurs on Spyder Python 3.6
Has to be False, not 'False', not false.

Thanks Allen, that removed the error. Now, to figure out why the data isn't displayed.
@mkepke Did you figure out why data isn't displayed? I'm having the same issue.
What development environment are you working in? I strongly recommend Jupyter.
The thinkplot functions you are using are just thin wrappers around matplotlib functions, so I suspect this is a problem with matplotlib in your environment.
@AllenDowney I was running in Spyder. I opened up Jupyter to give it a try, but am having the same problem.
The graph is printed without labels on the axes when I do: thinkplot.Hist(hist)
When I do: thinkplot.Show(xlabel='value',ylabel='frequency', legend=False)
A blank graph is printed (but the labels show up :)
I just figured it out I believe...
If you run (all in one block): hist = thinkstats2.Hist([1, 2, 2, 3, 5]) thinkplot.Hist(hist) thinkplot.Show(xlabel='value', ylabel='frequency')
It works like a charm.
If you run (all individually): hist = thinkstats2.Hist([1, 2, 2, 3, 5]) # enter
Then: thinkplot.Hist(hist) # enter
Then: thinkplot.Show(xlabel='value', ylabel='frequency') #enter
You get a blank graph with the last statement. Sorry about the confusion.
Glad you worked it out. What development environment are you using?

I was using spyder and typing (or copying/pasting) your code into the console. I then switched to JupyterLab, but was essentially doing the same thing. Executing the code from the console and executing line by line. When I would copy/paste chunks of code into the console and execute the entire chunk, it worked! I'm just getting into python so I'm sure it was misunderstanding on my part.
Got it. I will look for places to warn people about this issue.
Thanks!
