It is a symmetric distribution about its mean where most of the observations cluster around the mean and the probabilities for values further away from the mean taper off equally in both directions. WebNormal (Gaussian) Distribution is a probability function that describes how the values of a variable are distributed. 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. and/or scale the distribution use the loc and scale parameters.
