                                              Creating Charts and Graphics
                                             Using images in a chart offers unlimited potential for creativity. The key, of course, is to resist the temptation
                                             to go overboard. A chart’s primary goal is to convey information, not to impress the viewer with your artis-
                                             tic skills.
                                                       Using images, especially photos, in charts can dramatically increase the size of your work-

                                             Creating a thermometer chart
                                             You’re probably familiar with a “thermometer” type display that shows the percentage of a task that’s com-
                                             pleted. Creating such a display in Excel is very easy. The trick involves creating a chart that uses a single cell
                                             (which holds a percentage value) as a data series.
                                             Figure 20.34 shows a worksheet set up to track daily progress toward a goal: 1,000 new customers in a 15-
                                             day period. Cell B18 contains the goal value, and cell B19 contains a simple formula that calculates the
                                             sum. Cell B21 contains a formula that calculates the percent of goal:
                                                  =B19/B18
                                       FIGURE 20.33
                                      The top chart uses clipart, while the bottom chart uses a Shape that was copied to the Clipboard.
