Definition:
A data series is a group of related data entries. In a worksheet an individual data series is located in a column or row under a common heading such as Month or Average Temperature.
Individual data series are often plotted in charts and graphs. In charts or graphs where multiple data series are plotted each data series is identified by a unique color or pattern.
For example, in a bar graph the individual colored or patterned bars in the graph each represent a data series. In a line graph, each line shows the data from an individual data series.
Pie charts have only one data series. Each colored or patterned section of the pie represents an individual data point in the series.
