To learn more, see our tips on writing great answers. ax.set_xlabels( ['two', 'four','six', 'eight', 'ten']) This will display the text labels below the markers on the x axis. The rest of our code: With plt.xlabel and plt.ylabel, we can assign labels to those respective axis. By default matplotlib itself marks the data points on the axes but it has also provided us with setting their own axes having ticks and tick labels of their choice. The following are the steps to add x-axis labels to your graph: The following is the syntax for adding an x-axis label : The following are the parameters that were used: Use the xlabel() method in matplotlib to add a label to the plots x-axis.
