1. Consider the following descriptions of datasets. What style of chart would you suggest for each?

• 1. Web server hit counts by date
  2. Sales figures by salesperson per month
  3. Percentages of support tickets for the past year by company department
  4. The yield of a plot of bean plants against the plant's height, for several hundred plants

The answers are subjective, but the author suggests the following:

1. 1. A line or spline chart, as it would illustrate traffic trends
   2. A bar or stacked by chart, as this would allow you to compare salespeople over time
   3. A pie chart, since it represents a set of percentages adding up to 100
   4. A scatter plot, since you want to show a general trend of a large set of data

2. Which chart component has not been configured in the following code, and what will the result be?

   data_list = [
       qtc.QPoint(2, 3),
       qtc.QPoint(4, 5),
     ...
