isSpreadSheetFormat

public boolean isSpreadSheetFormat()

This flag notifies that the input result set should be treated as a spreadsheet. The first column in the input is assumed to be the "row label column". The other column headings (except the first) are called "column labels". The values in the remaining rows and columns are treated as cells in the spreadsheet. Before plotting the chart, data is transposed from the spreadsheet form into a tabular form. The new result set has three columns : RowLabel, ColumnLabel and Value. The RowLabel column only contains the values from the first input column. The ColumLabel column only contains values from the input column headings. Finally, each cell in the original spreadsheet is transformed into a distinct row, comprising the row label, the column label, and the value of that cell.

Such a transformation is useful when the various columns in a result set from a spreadsheet (e.g. Excel) need to be treated as different series for the same data category (denoted by the first column in the set). Note that the data types of all the columns (except the first) must be numeric and of the same type.
