A Chart Title of course is something that describes your chart. And PowerPoint charts do have an option to use a placeholder to contain
this Chart Title. However, before you go ahead and use this option, you must decide if you need this Chart Title placeholder or not. Here
are some guidelines that will help you make that decision.
The text used to label the chart axes in a chart is called an Axis Title. All chart types other than Pie and Doughnut have axes -- and
although Radar charts have an axis, there is no provision to add Axis Title for them. In all other chart types such as Column, Line, etc.,
Axis Titles are not visible by default.
Set Minimum and
Maximum Values on Value Axis
If your chart data values are not so much different from each other, the chart created using this data will not help your
audience to differentiate the series representing those values. Our sample data explores how people of different age brackets
choose their favorite colors. If you look closely at the data, you will realize that all values span between 285 and 365. So,
it makes no sense to even discuss any value lower than 250 or above 370 for this data set.
Change Major and Minor Units of Value Axis
While learning about chart axes, you will come across two terms, Major and Minor units. These are the intervals at which the axis
spaces itself -- as the name itself suggests, you can choose to space the axis at two levels: Major and Minor. PowerPoint sets
the Major and Minor units on its own -- many times, this may be exactly what you need. At other times, you may want to set specific
intervals for the Major and Minor units for several reasons.
Changing Axis Labels
Axis Labels are the labels for the Categories and Values on chart axes. So, where do these labels come from? Category axis labels reflect
the Category names within your data (typically within the built-in Excel sheet). Values on the other hand are determined by PowerPoint
based upon the maximum value in your data -- the minimum value is always set to zero. Of course you can change the Minimum and Maximum
values if you want.
