Parameters: datasetArray or a sequence of vectors. Make a violin plot. A box plot displays a summary of a set of data containing the minimum, first quartile, median, third quartile, and maximum. We start by defining the number of random observations we will draw from certain distributions, as well as setting the seed for reproducibility of the results. This is where the data is fed to the function. It is similar to Box Plot but with a rotated plot on each side, giving more information about the density estimate on the y-axis. The matplotlib.pyplot.violinplot() function makes a violin plot for each column of dataset or each vector in sequence dataset.Each filled area extends to represent the entire data range, with optional lines at the mean, the median . A violin plot is a hybrid of a box plot & a kernel density plot, which shows peaks in the data. A Violin plot is generally related to a boxing plot, but this plot also depicts the data's probability distribution function at various parameters. What I want to do is half -violin plot as here. A violin plot is a method of plotting numeric data. Below is a code snippet for plotting the number of ice creams sold during a week. The sides of the "violins" in a violin plot corresponds to a kernel density estimation (kind of like a histogram) flipped vertically.
