What’s the use of a plot, if the viewer doesn’t know what the numbers represent. Python newbie here. Zen | By seeing those bars, one can understand which product is performing good or bad. Detail: xerr and yerr are passed directly to errorbar(), so they can also have shape 2xN for independent specification of lower and upper errors. Stacked Bar Charts in Matplotlib (With Examples) A stacked bar chart is a type of chart that uses bars to display the frequencies of different categories. You may use the following syntax in order to create a bar chart in Python using Matplotlib: import matplotlib.pyplot as plt plt.bar (xAxis,yAxis) plt.title ('title name') plt.xlabel ('xAxis name') plt.ylabel ('yAxis name') plt.show () Next, you’ll see how to apply the above syntax in practice.
