A delta column calculates summaries against two
                                                    measures, and displays the difference between these
                                                    summaries. This difference can be indicated with a
                                                    numeric value displayed within the delta element and an
                                                    additional delta indication.

                                                    Delta columns are bound to two measures that provide
                                                    two values: the Actual value and the Target value. The
                                                    difference between these values is displayed in the
                                                    column.

                                  Delta             When you switch the column type to Delta, the data item
                                                    container is changed, to accept the Actual and Target
                                                    measures.
                                                    Values in the delta column can be displayed as text, or
                                                    represented by bars. To select between these modes,
                                                    open the Column Options window and select Value or
                                                    Bar. If bars are displayed, use the Always show zero
                                                    level check box to specify whether the bar's minimum
                                                    value is zero (checked) or an automatically selected
                                                    value that ensures that the difference between bars is
                                                    clearly displayed (unchecked).

                                                    A sparkline column visualizes the variation in summary
                                                    values over time.

                                                    The sparkline column is bound to a measure providing
                                                    sparkline values and to a dimension providing a date-
                                                    time interval.
                                  Sparkline
                                                    You can control sparkline appearance settings using the
                                                    Column Options dialog. To open this dialog, click the
                                                    column type indicator. In this dialog, you can control
                                                    various settings that affect how the sparkline is
                                                    displayed within a grid cell.

                                                    A hyperlink column allows you to display hyperlinks in
                                                    the Grid dashboard item. You can provide hyperlinks as
                                  Hyperlink         a separate data column. or they can be automatically
                                                    created at run-time from any column using the specified
                                                    URI pattern.

               When you drop a data item into the Columns section, the type for the new column is
               determined automatically, based on the data type.

               To change the column type, click the column type indicator. In the open Column
               Options window, select the required column type in the Column Type section.
