Bar Charts

Bar Charts

Bar Chart - Vertical

Guidelines:

• Bar charts should be converted into accessible tables.
• Briefly describe the chart and give a summary if one is immediately apparent.
• Provide the title and axis labels.
• It is not necessary to describe the visual attributes of the bars, e.g. dark blue, light blue, unless there is an explicit need such as an exam question referring to the colors.

Description:

Figure 1 is a bar chart that measures percentage of vaccination coverage in five states over one year, from Q3 2006 to Q2 2007. In each state, the coverage increases over time.

The data are summarized in the following table. All data are approximate.
