After you create a chart, you might want to change the data range on which it is based, or how this data is plotted. The following sections explain how you can do this.
By default, the columns of the datasheet form the data series. However, if you want, you can switch the data around so that the rows form the series. Figures 23-31 and 23-32 show the same chart plotted both ways so that you can see the difference.
What does the term data series mean? Take a look at Figures 23-31 and 23-32. Notice that there is a legend next to each chart that shows what each color (or shade of gray) represents. Each of these colors, and the label associated with it, is a series. The other variable (the one that is not the series) is plotted on the chart’s horizontal axis.
