Series
## Series
**Series** is the most frequently used feature in charts. Each chart contains one or more data series, and each series consists of a group of data points.
These examples demonstrate how to add a series to a chart, and how to specify settings for each series, such as:
- **BubbleScale** and **SizeRepresents** for bubble charts
- Configure **Series** format
- Change **Series Type**
- Add **Secondary Axis**
- **VaryByCategories** colors for single-series column charts
