Which property must be defined when configuring a single-value chart?

When configuring a single-value chart, it is essential to define the data value being represented. The data value is the core element that the chart is intended to visualize, as it indicates the specific metric or measurement that will be plotted on the chart. In a single-value chart, the focus is on displaying one key piece of information, such as a sales figure, a KPI, or any other singular value that is significant for analysis.

Defining the data value is crucial because it determines what information the user will see when they view the chart, making it necessary for the chart to convey its intended message effectively. Without specifying the data value, the chart cannot serve its purpose, as it would lack context and relevant information.

Other properties like data series, graph type, and axis labels are important for various types of charts, but for a single-value chart specifically, the defining characteristic that must be included is the data value, which centers the chart's function around that one specific measurement.
