Figure 122. Percentage bar chart
When constructing a bar, the space between the columns is 2/3 the width
of a column, the same spacing as a vertical column chart. You use the
same criteria the lesson discussed earlier to select the scale and
title. To construct a bar, you use the same procedure used to construct
a vertical column chart; however, you must remember to use the Xaxis
for the scale and the Yaxis for the data, maintaining a 2 to 3 ratio
for the chart.
You can also combine this type of chart with a table to help the reader
understand the data presented. Figure 123 shows a descriptive bar
chart comparing the percentage of aircraft not operationally ready (same
data as in figure 121).
