When this property is set (it is not set by default), the rows and columns in the DataSource will be transposed to render in the opposite way from which they are typically shown. Rows (series) become columns (items) and columns (items) will become rows (series).
This method can be used to alter a data source that doesn't initially conform to a chart's Data Requirements to become chartable. It can also invalidate a data source that previously met the requirements for a chart type, because the data will no longer do so (in its transposed state).
