Explanation
A gauge is a dashboard component type that shows a single value within a range of custom values. A gauge is useful for showing whether a metric, such as revenue or customer satisfaction, is within a desired range. For example, a gauge could show the current revenue as a needle pointing to a green, yellow, or red zone, indicating whether the revenue is above, below, or on target. A metric is a dashboard component type that shows a single value, such as the total number of accounts or the average deal size. A metric does not show a range of values. A chart is a dashboard component type that shows data in a graphical format, such as a pie chart, a bar chart, or a line chart. A chart is useful for showing the distribution or trend of data, but not a single value within a range.
