Line Charts

A line chart is used to analyze the data change trend in a certain period, which is reflected in the following aspects:

Increment or decrement
Increase/Decrease rate
Regularity of increase/decrease (such as periodic change)
Peak and valley values

Therefore, the line chart is the best choice for analyzing the data change trend over time. In addition, you can draw multiple lines to analyze the change trend of multiple groups of data in the same period, and then analyze the interaction and impact between data (such as in direct or inverse proportion).
