What is the difference between a vertical and horizontal bar graph?

Back

A vertical bar graph displays bars that rise vertically from the x-axis, while a horizontal bar graph displays bars that extend horizontally from the y-axis.

How can you determine the total value represented in a bar graph?

Back

To determine the total value, you can add the values represented by each bar if the graph shows individual categories.
