WebbA density curve, or kernel density estimate (KDE), is an alternative to the histogram that gives each data point a continuous contribution to the distribution. In a histogram, you might think of each data point as pouring liquid from its value into a series of cylinders below (the bins). WebbA histogram is a representation of the distribution of data.

WebbSmoothed density estimates. Source: R/geom-density.r, R/stat-density.r. Computes and draws kernel density estimate, which is a smoothed version of the histogram. This is a useful alternative to the histogram for continuous data that comes from an underlying smooth distribution.

Webbhistfit(data) plots a histogram of values in data using the number of bins equal to the square root of the number of elements in data and fits a normal density function. example histfit( data , nbins ) plots a histogram using nbins bins and fits a normal density function. WebbIf density is also True then the histogram is normalized such that the last bin equals 1. If cumulative is a number less than 0 (e.g., -1), the direction of accumulation is reversed. In this case, if density is also True, then the histogram is normalized such that the first bin equals 1. bottom array-like, scalar, or None, default: None
