A bar plot is a graph plot in which there are bars in the graph. To the order argument, we need to provide the x-axis variable in the order we want to plot. In addition to x-axis variable and kind=”count”, we can use hue argument with another variable. Plotting a Bar Plot in Seaborn is as easy as calling the barplot() function on the sns instance, and passing in the categorical and continuous variables that we'd like to visualize: import matplotlib.pyplot as plt import seaborn as sns sns.set_style('darkgrid') x = ['A', 'B', 'C'] y = [1, 5, 3] sns.barplot(x, y) plt.show() Here, we've got a few categorical variables in a list - A, B and C.
