Density plots are a useful way to visualize the distribution of a dataset. They are similar to histograms but use a continuous curve to represent the data distribution. In Python, you can create density plots using various libraries such as Matplotlib, Seaborn, and SciPy.
Using Seaborn's kdeplot() Function
The easiest way to create a density plot in Matplotlib is by using the kdeplot() function from the Seaborn library. Here is a basic example:
import seaborn as snsimport matplotlib.pyplot as plt# Define datadata = [2, 2, 3, 5, 6, 6, 7, 8, 9, 10, 12, 12, 13, 15, 16]# Create density plotsns.kdeplot(data)plt.show()You can adjust the smoothness of the density plot using the bw_method argument. Lower values make the plot more "wiggly," while higher values make it smoother:
# Create density plot with low bw_method valuesns.kdeplot(data, bw_method=0.3)plt.show()# Create density plot with high bw_method valuesns.kdeplot(data, bw_method=0.8)plt.show() python - How to create a density plot - Stack Overflow
The density plot can also be created by using matplotlib: The function plt.hist(data) returns the y and x values necessary for the density plot (see the documentation …
