Which graph shows trend of data across time?
Line graphs are used to display data or information that changes continuously over time. Line graphs allow us to see overall trends such as an increase or decrease in data over time. Bar graphs are used to compare facts.
How do you show trends in Excel?

Why are bar charts and pie charts used in statistics?
