What is a Data Series in Excel?

A data series is a collection of consecutive values or numbers in a column on a spreadsheet. We can create data series by plotting a graph from an initial series of data, then, we can create another series of data and highlight it along with the pre-existing data series. This tutorial would teach us how to add data series to a spreadsheet.

When we click on the chart, it will highlight both the Temp. and Time columns, indicating the source of data. We will now drag the Fill handle (the box at the bottom-right when we click a cell) of the highlighted titles in Cells A3 and B3 over the new column created in Cell C3 to create the data series on the chart.
