I just discovered catplot in Seaborn. All trademarks mentioned are the property of their respective owners. A few explanation about the code below: input dataset must provide 3 columns: the numeric value (value), and 2 categorical variables for the group (specie) and the subgroup (condition) levels. Before trying to build one, check how to make a basic barplot with R and ggplot2. Bar graph or Bar Plot: Bar Plot is a visualization of x and y numeric and categorical dataset variable in a graph to find the relationship between them. The bars will have a thickness of 0.25 units. Note that you can easily turn it as a stacked area barplot, where each subgroups are displayed one on top of each other. Barplot is used to show discrete, numerical comparisons across categories. In the final Seaborn barplot example, you will learn how to create multiple barplots. The second call to pyplot.bar() plots the red bars, with the bottom of the blue bars being at the top of the red bars. In most cases, it is possible to use numpy or Python objects, but pandas objects are preferable because the associated names will be used to annotate the axes.

Along with that used different functions and different parameter. Note that you can easily turn it as a stacked area barplot, where each subgroups are displayed one on top of each other. The optional bottom parameter of the pyplot.bar() function allows you to specify a starting value for a bar. With the grouped bar chart we need to use a numeric axis (you'll see why further below), so we create a simple range of numbers using np.arangeto use as our xvalues.
