How to draw a discounted statistical graph of the highest and lowest temperatures for a week

The method of discounting statistical graphics of the highest and lowest temperatures for a week is:

1. Use the data on the vertical axis to represent the temperature. The unit is ℃, and each grid represents 5℃. Use the data on the horizontal axis to represent the days from Monday to Sunday.

2. Draw points and connect lines on the graph to complete a statistical graph of the changes in maximum and minimum temperatures for this week; to complete a statistical graph of maximum and minimum temperatures.

3. Use a compound line statistical chart and use lines (or solid lines or dotted lines) of different colors to represent the maximum temperature and the minimum temperature.
