All charts, whether in column, bar, line, pie, area, or scatter format, contain series data, category data, and value data. The following column chart explains the difference between series and categories.
When Microsoft Excel creates a chart from a worksheet, it assigns either the worksheet rows as the series data (and the columns as the category data), or the worksheet columns as the series data (and the rows as categories). If there are fewer rows than columns, then the rows become the series. However, if there are fewer columns than rows, then the columns become the series. If there are an equal number of rows and columns in the range of cells, then the rows become the series.
This algorithm minimizes the number of series on the chart. For example, the following column chart . . .
. . . can be created from either of the two following worksheets.
In the second worksheet shown here, January and February are the series (because there are fewer rows than columns), and Chicago, Dallas, and Boston are the categories. In these two worksheets, values for each series appear at three locations on the chart.
If you add sales data for March and April, the series are now Chicago, Dallas, and Boston, and the categories are January, February, March, and April. Microsoft Excel automatically exchanges the series and categories to minimize the number of series.
