## data series

A data series is a set of related values that are plotted on a chart.

Data series are represented differently in different kinds of charts:

*Column charts and bar charts:*A data series is represented by a series of bars in the same fill (color or texture).*Line charts (also called graphs):*A data series is represented by a single line.*Area charts:*A data series is represented by an area shape.*Pie charts and donut charts:*Only a single data set (the first data point in each series) is represented on the chart.*Scatter charts:*Two columns of data are used to plot values for a single data series. Each pair of values determines the position of one data point.*Bubble charts:*Three columns of data are used to plot values for a single data series. Each triplet of values determines the position and size of one data point (bubble)—the first two values (*x*and*y*) determine the position (or coordinates) of the bubble, and the third value (*z*) determines the size of the bubble.
