To include qualitative ranges in a bullet chart, what must be included in the worksheet?

To incorporate qualitative ranges in a bullet chart, it is essential to include numeric columns in the worksheet. Bullet charts are designed to visually represent performance against qualitative ranges, such as good, average, or poor. These qualitative indicators are usually displayed as bands behind the actual data represented in the bullet chart.

Numeric columns provide the necessary data points that indicate where the actual performance stands in relation to the qualitative ranges. The bullet chart effectively visualizes how the numeric value fits within these predefined ranges, enabling viewers to quickly assess performance.

While text columns, image columns, and formula columns may serve different purposes in a worksheet, they do not directly contribute to the quantitative aspect required for bullet charts. Text columns might offer descriptive labels, but without numeric data, the chart itself wouldn’t be functional. Similarly, image columns can add visual elements but do not provide the numerical context needed for the chart's primary purpose. Formula columns might help in calculations but are not inherently relevant for establishing the qualitative ranges. Thus, numeric columns are fundamental for establishing the necessary data structure to create an effective bullet chart.
