This allows us to then define an. So let me draw a probability distribution, or they call it its probability density function. Density curves with adjust set to.25 (red), default value of 1 (black), and 2 (blue) in this example, the x range is automatically set so that it contains the data, but this. A basic histogram can be created with the hist function. The total area under the curve results probability value of 1. Web we are breaking out the density plot into multiple density plots based on species.
Hence the total area under the density curve will always be equal to 1. Web the area under a density curve equals 1, and the area under the histogram equals the width of the bars times the sum of their height ie. Web we are breaking out the density plot into multiple density plots based on species.
