What is a data series in the context of a chart?

A data series in the context of a chart refers to a set of related data points that are visually represented. This means that when creating a chart, the data series comprises multiple values that share a common characteristic, typically related to the same category or time period.

For example, if you are charting monthly sales figures for different products, each product would be a data series that includes all of its sales figures over the months. This allows viewers to easily compare these related values and discern trends or patterns within the data. Therefore, the idea of a data series helps organize and visually convey information in a way that is meaningful and interpretable in the context of a chart.
