Create and Interpret Column Graphs II
Lesson

Column graphs help to paint a picture of the data we are looking at, making it visually very simple to compare information. The way we create a column graph doesn't really change, but what we include in it may change, so once you learn how to create one, you can change it slightly for the next time.

Worked examples
