The prefix and suffix help you define a number as currency, capacity, length, mass, etc. They can be added to the axes, labels, and tooltips of a chart, as well as value labels of a map.
- Select a chart or map by clicking on it.
- Expand the Data format tab, where you will find the option to enter a prefix and/or suffix.
- Choose whether you wish to apply the prefix/suffix to the chart axis, to value labels, or to the tooltips. With maps, the prefix/suffix will be applied only to value labels.
