And I want to plot the line chart on the pair. pyplot. We'll show an example of why it might matter a bit later. Then by using plt.plot () method we plot the line chart. Let's have a look at an example: # Import Library import matplotlib.pyplot as plt # Define Data x = [0, 1, 2, 3, 4] y = [2, 4, 6, 8, 12] # Plotting plt.plot (x, y) # Add x-axis label plt.xlabel ('X-axis Label') # Visualize plt.show () The following code shows how to add a title to a plot in Matplotlib: import matplotlib.pyplot as plt #define x and y x = [1, 4, 10] y = [5, 11, 27] #create plot of x and y plt.plot(x, y) #add title plt.title('My Title') Note that you can also use the fontsize and loc arguments to specify the font size and location .

How to change imshow axis values (labels) in matplotlib ? The only "issue" is that it's using the "stateful" API (not the Object-Oriented API); that sometimes doesn't matter but in general, it's recommended to use OO methods where you can.
