Question

use vertical bars to present data

Answer 1

Answer:

The double (or group) vertical bar graph is another effective means of comparing sets of data about the same places or items. This type of vertical bar graph gives two or more pieces of information for each item on the x-axis instead of just one as in Figure 1

Vertical bar graphs use the x-axis for labeling categories, while numeric data is measured along the y-axis. This type of chart is useful if one axis does not have numeric data. In a vertical bar chart, the y-axis includes numeric information, such as the number of client computers or jobs in each status.
