Illustration of the bar chart in the Figure 3. Labels point to features of the chart. The text reads: Title – all bar charts need a title to explain what data is being shown. Key – bar charts with more than one bar for each section will need a key so it is clear what each bar refers to. Bars – whilst this seems like stating the obvious, your bar graph needs accurately drawn bars that are all the same width. Bar labels – each bar must be clearly labelled. Horizontal axis title – all bar charts need a title along the axis to describe what the information along the axis relates to. Numbered scale – the axis must be numbered with a sensible scale, the numbers could go up in 1s, 2s, 5s, 10s etc. depending on what is appropriate for the data. Vertical axis title – all bar charts need a title along this axis to describe what the information along this axis refers to.
