When you create a chart, Excel checks the number of rows and columns.
In the example below, there are six rows (in Column A, Zone) and three columns (years).
In a chart created automatically by pressing F11, rows from the data table are created on the category axis.
To switch from rows to columns in the category axis, select the chart, and from the Chart menu, select Source Data. In Series in, select Columns. Screenshot // Changing the Layout of the Chart from Rows to Columns and Vice Versa in Microsoft Excel
