Ploting Matplotlib Histogram In Python

Solution 1:

Try to debug your code. You will find y1 is a list of strings, so plt.hist(y1) will raise

TypeError: len() of unsized object

TypeError raised when an operation or function is applied to an object of inappropriate type.

That means you should use float or int, so try to run this:

y1 = [float(interval) for op, response, intervalin pieces]
