Which element is NOT involved in configuring single-value charts?

In the context of configuring single-value charts, setting axis titles is not a fundamental element involved in the chart's data representation. Single-value charts are primarily concerned with displaying a single metric or data point clearly and effectively, which means the emphasis is on defining the data value itself, establishing comparative values for context, and deciding how the user can interact with that information, such as through drill behavior.

The focus of single-value charts is on the data visualization rather than the axis labels. While axis titles can enhance understanding of what the data represents, they are not necessary for the functional aspects of the chart's configuration. The primary aim is to render the single value in an impactful way, without the additional cognitive load that titles might introduce.

Involving elements like defining the data value and comparative values directly affects how the chart conveys information. Therefore, the other elements listed are essential for configuring single-value charts, while setting axis titles is ancillary and not essential to the core function of these types of charts.
