問題文
A team wants one dashboard that answers both whether the fleet as a whole is healthy and which individual member is worst. Which combination of chart types and functions does that?
選択肢
- A table chart alone, because it shows every member as a row and every metric as a column so it answers both of the questions at once, leaving the aggregation aside for the moment.
- A single value chart for the population view and a heat map for the worst members, because a single value chart aggregates automatically and a heat map highlights the highest values in red without a function at all.
- Two separate dashboards, because the two questions cannot be answered on one screen at the same time; each of them needs a screen of its own to sit on.
- A percentile or aggregate chart for the population view, and a list chart with the top function for the worst members, because a list chart holds up to one hundred items and the top function narrows a large population to a ranking.
