If you actually want to see "how many have the same count", rather than a representation of the disribution, then you'll either need to set the bins kwarg to be df["count"].max()-df["count"].min() - or do as you said and count the number of times you get each count and then create a bar chart. For example, for the data in this problem, the mean and standard deviation of the best-fitting normal distribution can be found as follows: The function xlim() within the Pyplot module of the Matplotlib library is used to obtain or set the x limit of this axis.
