Sample Solution: Python Code: The entire proportion of the defined dataset is represented by the graph's area. Let's start with a simple pie. Later, this array will be passed to the Pyplot function as an input. The pie chart is made using the following codes below: labels = df_score_2.index. This line sets the x and y-axis scales as equal, which forces the pie chart into a circle shape. We can use the following arguments to customize the appearance of the pie chart: autopct: Display percentages in pie chart; colors: Specify colors to use in pie chart; title: Add title to pie chart; The following code shows how to use these .

Making the pie chart. Matplotlib Bar Chart. If you specify the format string, then it must be enclosed within the % sign. The size of the item, or 'wedge' is proportional to the sum of all items in the Pie chart. If we want to set the background color of the figure and set axes to be transparent or need to set the figure area to transparent we need the set_alpha () method.
