Give a name to x-axis and y-axis using .xlabel() and .ylabel() functions. Give a title to your plot using .title() function. Finally, to view your plot, we use .show() function.

Plot data from a . txt file using matplotlib Set the figure size and adjust the padding between and around the subplots. Initialize empty lists for bar_names and bar_heights. Open a sample . txt file in read "r" mode and append to bar's name and height list. Make a bar plot. To display the figure, use show() method.
