The PivotChart works the same as the PivotTable. For example, if you
click the Axis Fields button in the PivotChart Filter Pane, you can add or
remove categories from the chart. The pivot chart is also linked to the Pivot-
Table, so any changes you make to layout or formatting of the chart are auto-
matically refl ected in the PivotTable.
Column charts are often used by statisticians when the need is to show the
relative sizes of the groups. For example, it’s quickly apparent from the chart
that the mathematics and science departments have the highest representa-
tion of any category in the data set. What is not clear from the chart is the
size of each group compared to the whole. For example, does the MathSci
group make up more than half of the total respondents? It’s not so easy to
determine that kind of information from the column chart. To deal with that
problem, we can have Excel add the counts to the chart.
To add counts to the column chart:
