                                  Part III
                                              Creating Charts and Graphics
                                             The chart title is a text element that you can select and edit. Alternatively, you can link the chart title to a
                                             cell so the title always displays the contents of a particular cell. To create a link to a cell, click the chart title,
                                             type an equal sign (=), and click the cell. Excel displays the link in the Formula bar. In the example, the
                                             contents of cell A1 is perfect for the chart title.
                                             Experiment with the Chart Tools ➪ Layout tab to make other changes to the chart. For example, you can
                                             remove the grid lines, add axis titles, relocate the legend, and so on. Making these changes is easy and
                                             intuitive.
                                             Trying another view of the data
                                             The chart, at this point, shows six clusters (months) of three data points in each (age groups). Would the
                                             data be easier to understand if we plotted the information in the opposite way?
                                             Try it. Select the chart and then choose Chart Tools ➪ Design ➪ Data ➪ Switch Row/Column. Figure 19.6
                                             shows the result of this change. I also selected a different layout, which provides more separation between
                                             the three clusters.
                                                       The orientation of the data has a drastic effect on the look of your chart. Excel has its own
                                          NOTE
                                           NOTE
                                                       rules that it uses to determine the initial data orientation when you create a chart. If Excel’s
                                             orientation doesn’t match your expectation, it’s easy enough to change.
                                             The chart, with this new orientation, reveals information that wasn’t so apparent in the original version. The
                                             <30 and 30-49 age groups both show a decline in satisfaction for March and April. The 50+ age group didn’t
                                             have this problem, however.

                                             Trying other chart types
                                             Although a clustered column chart seems to work well for this data, there’s no harm in checking out some
                                             other chart types. Choose Design ➪ Type ➪ Change Chart Type to experiment with other chart types. This
                                             command displays the Change Chart Type dialog box, shown in Figure 19.7. The main categories are listed
                                             on the left, and the subtypes are shown as icons. Select an icon, click OK, and Excel displays the chart
                                             using the new chart type. If you don’t like the result, select Undo.
                                             Figure 19.8 shows a few different chart type options.
