In Tanium Trends, which chart is best for comparing related values as percentages of a whole over time?

The Stacked Area Chart is particularly effective for comparing related values as percentages of a whole over time because it provides a visual representation of how different components contribute to the overall total. Each area in the chart represents a different category, with the total height of the stacked areas indicating the aggregate value at any given point in time.

This format allows viewers to not only see the trend of each individual category but also to gauge how they relate to the total over time. The stacking of areas makes it easy to identify the proportions of each category relative to the whole, highlighting changes in composition visually.

In contrast, a Bar Chart is typically used for comparing quantities in individual categories rather than illustrating how they form a whole over time. A Number Chart presents data in a numerical format, lacking the visual context necessary for understanding trends over a period. A Line Chart could show trends over time effectively, but it does not inherently convey the concept of parts-to-whole relationships as clearly as a Stacked Area Chart does. Thus, for the specific need to compare values as percentages of a whole over time, the Stacked Area Chart is the most suitable option.
