Titles and Axis Labels
A chart nobody can read has failed, however good the data. Three lines fix most of the problem: a title that says what the chart shows, and a label on each axis that says what is measured and in which unit.
Use ax.set_title(...), ax.set_xlabel(...) and ax.set_ylabel(...). A strong title states the finding ("Sales doubled in six months"), not just the topic ("Sales"). Put units in the label, for example "Revenue (GH cedis)".
Which call sets the label under the horizontal axis?
Give the chart the title 'Rainfall', the x label 'Month' and the y label 'Millimetres', then print the three texts on separate lines (use ax.get_title(), ax.get_xlabel(), ax.get_ylabel()).
