Also in line 9, figsize=(5,5) command is used here, to resize the output figure window. Next, plot the pie chart using matplotlib. A pie chart is one of the charts it can create, but it is one of the many. You can create the figure with equal width and height, or force the aspect ratio to be equal after plotting by calling ax.set_aspect('equal') on the returned axes object.. This adds a legend on top of the plot. Demo of a basic pie chart plus a few additional features. The pie chart does not 'know' that you want all items with same product name grouped and summed over in your chart. Matplotlib is a widely used Python based library; it is used to create 2d Plots and graphs easily through Python script, it got another name as a pyplot. The documentation suggests I should use autopct to do this.. autopct: [ None | format string | format function ] If not None, is a string or function … Matplotlib is a multi-platform data visualization library built on NumPy arrays and designed to work with the broader SciPy stack. To add a legend use the plt.legend() function. It is among the first choices to plot graphs for quickly visualizing some data. Python Matplotlib : Pie Chart. Matplotlib is a Python library used for plotting. For our example, the DataFrame (with the tasks data) would look like this: And here is the complete Python code to create the pie chart based on the data in the DataFrame: Once you run the code, you’ll get the same pie chart: You may then choose to style the chart using the following syntax: You’ll then get the following styled chart: For other types of charts, you may want to check the following source that explains the steps to create scatter, line and bar charts using matplotlib. The label will be placed inside the wedge. For this, we’ll use the groupby() function with the trend column to aggregate all days with the same trend into a single group before plotting the pie chart.

The area of the wedge is determined by the length of the arc of the wedge. Solution is to show string values as labels and range(len(x)) would display values through 1 to 5 in x … The fractional area of each wedge is given by x/sum(x). As we don’t have the autopct option available in Seaborn, we’ll need to define a custom aggregation using a lambda function to calculate the percentage column. 2.4. Matplotlib supports pie charts using the pie() function. First import plt from the matplotlib module with the line import matplotlib.pyplot as pltThen you can use the method plt.pie() to create a plot.
