Libraries
First, you need to install the following librairies:
- seaborn is used for creating the chart
- matplotlib is used for customization
import seaborn as sns
import matplotlib.pyplot as pltDataset
The dataset we will use is the iris dataset, which we can easily download with seaborn:
df = sns.load_dataset('iris')Violin plot
Fortunately, it's a very light syntax to create a violin plot with seaborn thanks to the violinplot() function:
# set a grey background (use sns.set_theme() if seaborn version 0.11.0 or above)
sns.set(style="darkgrid")
# Just switch x and y
sns.violinplot(x=df["species"], y=df["sepal_length"])
plt.show()
Flipped violin plot
Flipping this graph is actually quite simple, as all you have to do is exchange the arguments x and y.
# set a grey background (use sns.set_theme() if seaborn version 0.11.0 or above)
sns.set(style="darkgrid")
# Just switch x and y
sns.violinplot(y=df["species"], x=df["sepal_length"])
plt.show()
