In today’s recipe we’ll learn the basics of Seaborn plots customization. The steps below are show using a scatterplot example but for the most they are relevant for any other chart type: barplots, boxplots, heatmaps, lineplots, histplots (histograms) etc’.
We’ll use our simple deliveries dataset. If you are that you can download from here to follow along.
Let’s start by initializing the dataframe:
#Python import pandas as pd import seaborn as sns sns.set_style('whitegrid') deliveries = pd.read_csv('../../data/del_tips.csv')
Let’s quickly define a Seaborn sns scatterplot:
scatter, ax = plt.subplots(figsize = (10,7)) ax =sns.scatterplot(x = 'del_tip_amount', y ='time_to_deliver', data=deliveries, hue='type')
Note: We have used the figsize parameter to specify a custom plot size for our scatter.
Obviously, we need to customize the chart to increase readability.
Step 1: Set chart axes labels in Seaborn
Let’s start by defining labels for the axes instead of those being provided by default. We’ll also increase the font size.
ax.set_ylabel('Delivery Time (min)', fontsize = 15) ax.set_xlabel ('Tip Amount ($)', fontsize = 15) scatter
Step 2: Set sns plot titles
Next we’ll define a title for the chart itself. Here’s the very simple code to use:
ax.set_title('Tips by delivery time)', fontsize = 18) scatter
Step3: Define Seaborn axes limits
We might as well like to modify the axes limits to focus on some outlier results.
ax.set_xlim(left=14, right=20) ax.set_ylim(bottom=25, top=40) scatter
Note: Here’s a more elaborated Seaborn axis rages setting example.
Step 4: Setting chart legend locations
As you can see above, the lengend is not optimally located in the chart. For completeness, here’s a thorough tutorial on set your legend position in a Seaborn plot.
