Setting Axis Scale Options
To control how an axis appears (other than just whether or not it appears at all), choose
More Axis Options from the submenu. The options for axes are covered in the following
sections.
Setting Axis Scale Options
The scale determines which numbers will form the start point and endpoint of the axis line.
PowerPoint 2013 calls the scale the bounds of the axis because the minimum and maximum
values on the scale defi ne lower and upper boundaries for the axis.
Changing the axis scale can make a big difference in how an audience perceives the same
data. For example, take a look at the chart in Figure 12.27. The bars are so close to one
another in value that it is diffi cult to see the difference between them. Compare this chart
to one showing the same data in Figure 12.28, but with an adjusted scale. Because the scale
is smaller, the differences now appear more dramatic.
FIGURE 12.27
This chart does not show the differences between the values very well.
PowerPoint’s charting feature has an automatic setting for the scale that is turned on by default. However, you may
sometimes want to override this setting for a different effect, such as to minimize or enhance the difference between
data series. This is a good example of “making the data say what you want.” For example, if you wanted to make the
point that the differences between three months were insignii cant, then you would use a larger scale. If you wanted
to highlight the importance of the differences, then you would use a smaller scale.
