What is a requirement for a KPI to be displayed as a meter?

The requirement for a KPI to be displayed as a meter is that it must first be displayed in the KPI portlet. The KPI portlet is a specific component on the NetSuite dashboard that is designed to showcase key performance indicators, and displaying a KPI here is a necessary step for it to be visualized as a meter. This ensures that the KPI is properly defined and accessible within the dashboard context.

While other choices may pertain to aspects of KPIs or dashboard configurations, they do not specifically address the requirement for meter visualization. For instance, saving a KPI in the analytics dashboard may be a useful step, but it does not guarantee meter display. Similarly, having historical data is beneficial for understanding trends but does not directly influence the visual representation. Finally, while numerical values are typically used for KPIs, this alone does not ensure that the KPI will be displayed as a meter unless it has already been placed in the KPI portlet. Thus, the correct answer highlights the procedural aspect necessary for meter display functionality.
