How To Make A Histogram From A List Of Data

Well I think matplotlib got downloaded but with my new script I get this error: /usr/lib64/python2.6/site-packages/matplotlib/backends/backend_gtk.py:621: DeprecationWarning: U

Solution 1:

Automatic binning

how to make 200 evenly spaced out bins, and have your program store the data in the appropriate bins?

The accepted answer manually creates 200 bins with numpy.arange and numpy.linspace, but there are functions for automatic binning:

• numpy.histogram

  Returns edges that work directly with pyplot.stairs (new in matplotlib 3.4.0):

  values, edges = np.histogram(data, bins=200)
  plt.stairs(values, edges, fill=True)
  

• pandas.cut

  Returns bins that work directly with pyplot.hist:

  _, bins = pd.cut(data, bins=200, retbins=True)
  plt.hist(data, bins)
  

  

---

If you don't need to store the bins, then skip the binning step and just plot the histogram with bins as an integer:

1. pyplot.hist

   plt.hist(data, bins=200)
   

2. seaborn.histplot

   sns.histplot(data, bins=200)
   

3. pandas.DataFrame[.plot].hist or pandas.Series[.plot].hist

   pd.Series(data).plot.hist(bins=200)
