Here is the explanation for the preceding code:
This is the first plot:
- g = sns.PairGrid(snacks_sales_items, hue='Promotion', hue_kws={"marker": ["^", "D"]},palette={'Yes': 'blue', 'No': '#00a99f05'}) creates the grid for all the variables in the dataset:
- hue_kws={"marker": ["^", "D"]} specifies the markers to be used for Yes and No values of the hue variable Promotion
- palette={'Yes': 'blue', 'No': '#00a99f05'} specifies the color codes to be used for the hue variable unique values
- g.map(plt.scatter, edgecolor='k', s=50) plots scatter plot on each of the plots on the grid:
- edgecolor='k' specifies black for the edges of points on the scatter plot.
- s=50 specifies the size of the points/markers on the scatter plot.
- g.add_legend() ...
