What is a density plot?
Density plots are a type of data visualization, used to show the distribution of a set of continuous data points. They are best used when you are trying to understand the shape of the distribution of some data over a continuous interval or time period. Instead of plotting data directly, density plots use an algorithm to estimate the shape of the distribution first, before drawing it.
The chart is a variation of the histogram, but it uses an algorithm to smooth out the noise and therefore showing a smoother shape to the distribution. The peaks of a density plot help audiences see where values are concentrated over the interval.
It can therefore show you important features of the data distribution including, the mean, median, mode, skewness, and any outliers. For this reason, density plots are often used in fields such as statistics, data analysis, and research.
When creating a density plot it is best to start with raw data – values that show observations of a particular quantity. This could include, number of hours spent online, the average price of tomatoes each day for a year, the number of visitors to a museum each day over a year, etc.
For a density plot to be effective, you should have enough observations in your dataset for it to be a meaningful estimate of the distribution. Avoid using figures that are aggregated or only form a small set.

Density plot FAQs
What is a density plot?
A density plot shows the distribution of data for a variable over a time period or continuous interval. The density plot is a smoothed variation of a histogram and uses kernel smoothing to smooth out noise in the data. The peak of the density plot shows where values are the most concentrated over time. Density plots are also known as a Kernel density plot or a density trace graph.
What is a density plot vs histogram?
Density plots are smoothed variations of histograms. A histogram shows values from a selected column as binned distribution in the form of bars. A density plot takes this and uses kernel smoothing to smooth out the noise. This helps form a smooth curve across bins which helps create a more defined distribution shape.
Density plots can be preferred to histograms because they are better when you want to determine the distribution shape. This is because they are not affected by the number of bins (bars on the histogram). For example, it would be difficult to form a distribution shape from a histogram with a few bins, but possible with a density plot.
How do you analyse a density plot?
Looking at the density curve on a density plot should give you an idea of the shape of distribution. The peak of the density curve is where the values are most concentrated. However, a density plot may also have more than one peak of frequently occurring values. If a density curve has only one peak, the distribution is described as unimodal. If it has two peaks, it is called a bimodal distribution.
Looking at whether the curve skews to the left or right also indicates the location of the mean and median. If a density curve has no skew, the mean is equal to the median. If it skews left, the mean is less than the median. If it skews right, the mean is greater than the median.
