Practice: Telling a Story with a Chart
Pull the course together. Given a month of shop data, produce one clear chart with a finding in the title, labelled axes, a reference line, and a legend, then check its parts.
Work in this order, as a professional would: decide the question, choose the chart, draw it, label it, then add the one annotation that guides the reader.
Which of these makes the best chart title?
Draw both series with labels 'Online' and 'Walk-in', add a legend, set the title to 'Orders per day', then print the title and the legend texts on one line separated by ' | ' (build it with ax.get_title() + ' | ' + ', '.join(t.get_text() for t in ax.get_legend().get_texts())).
Finish the quick check (and any code exercise) to complete this lesson, or mark it done yourself.
