proportional to their time value difference (a non Time Aware Axis shows all items using the
same difference between them). The Time Aware feature only implements an alternative
visualization of source data and does not affect the way how the data is aggregated and computed
items are calculated. That is, the data processing in chart section which includes dividing data
into categories and calculating fact data does not depend on whether the Time Aware feature is
activated. In particular, the behavior of the “Chart This Pivot”, “Pivot This Chart” and “Add
Computed Item” actions do not change.
The Line Charts is the main application area of this feature; however it is available in almost all
existing chart types. Scatter/Bubble charts do not include this option because they are already
“time aware” (essentially, value aware) by nature. Both have two fact axes which are continuous
The Time Aware axis can only be used under specific conditions:
The X axis should have a date/time category to display, which becomes a dedicated Time
Only one category should be on the X-Axis. If you add multiple categories, even if they are
ate/time categories, the feature is rendered inactive.
The Time Aware axis is not available for pie, scatter and bubble charts.
The Time Aware Axis is considered active if the conditions in the list above are met, and the
Time Aware option on the Label Axis dialog is not explicitly disabled. You can turn on or off
the feature. If you turn off the feature, the X axis remains discrete as in previous versions. By
default the feature is turned off for Interactive Reporting document files older than Release 9.3.
Charts created in Release 9.3 and later have the feature enabled.
Since the Time Aware Axis assumes that all axis labels are in ascending order, the sort order
option is disabled.
To create a Time Aware axis:
Check the Time Aware option on the Label Axis tab of General properties.
Drag a date/time item from the Catalog pane to the X pane in the data layout.
Drag a value item from the Catalog pane to the Facts pane in the data layout.
A ribbon chart is very similar to a line chart, but with a few visual differences. In ribbon chart,
values in the y axis determine the height of the line, and values in the x axis itemize the line
sections. You can create multiple lines by adding items to the z axis.
