Sometimes bar graphs have text labels along the X axis.
To use text labels on the X axis:
A | B | C | |
1 | cars | 1000 | 3000 |
2 | boats | 2000 | 4000 |
3 | trains | 300 | 500 |
4 | planes | 4000 | 6000 |
This data might represent how far you traveled each of the past two years using cars, boats, trains, and planes, respectively. Selecting and plotting this data will produce a graph containing two interspersed bars (of different colors). A bar of each color will be centered over each text label, and will have a height proportional to the number of miles traveled using that mode of transportation over the past two years.
