What must be defined in order to display a chart on a worksheet?

To display a chart on a worksheet, it is essential to define a chart first. A chart serves as the graphical representation of data, allowing users to visualize and analyze the information effectively. Before any visual representation can be made, the chart itself must be created based on the data set. This includes specifying the type of chart (e.g., bar, line, pie) and the relevant data range that the chart will represent.

While data input methods, worksheet functionality, and text labels can play significant roles in the overall worksheet environment and usability, they do not directly relate to the requirement for displaying a chart. Without designing a chart, no visual representation of data can be established on the worksheet. Thus, the definition of a chart is key to ensuring that the visualization can be generated and rendered successfully.
