Each year's percent is represented by one vertical column. Each column is labelled along the horizontal axis of the graph. The vertical axis has a scale that shows the percent value of each column.
A Bar or Column Graph should have a good, descriptive title. Each axis (horizontal and vertical) should be clearly labelled and have an appropriate scale. In this case, the percent ranges from 1.6% to 5.0%. The scale goes from 0% to 6.0% in 1.0% intervals.
The bars and columns can be coloured or can be textured. In the examples above and on the next page, we have used different colours and textures. You could make a different colour or texture for each assignment or example that you do in this lab .
We can illustrate the same data by using a Bar Graph. Each horizontal bar represents a year and each year is labelled on the vertical axis The horizontal axis now has a scale for the percent value of each year.
