A bar plot or bar chart is a graph that represents the category of data with rectangular bars with lengths and heights that is proportional to the values which they represent. Matplotlib uses the default color cycler to color each wedge and automatically orders the wedges and plots them counter-clockwise. To adjust the tick frequency of the two axes separately, we use the set_xticks() function. We want to adjust the tick frequency on the axis level if we have multiple plots in a figure region. We set the value of axis and pad to x and 30, respectively, as parameters. Read: Add text to plot matplotlib in Python.
