# Series metrics [](https://geoffbullen.github.io/smaply-knowledge/docs/documentation/metrics/types-of-metrics#series)Series metrics involve a sequence of data points collected over a period or categorically. This type allows for detailed analysis and visualization of trends, changes, and progressions in your data. For example, tracking monthly visitors over a year.

**Horizontal bar:** Similar to the bar chart but with horizontal bars, ideal for long category names.
