The gauged
graph display applies a range to a standard graph display such as
bar graph or line graph. For the best results, the data model should
return only one value for each unique value in the
Category
label data column, thereby avoiding aggregation of the
data. The category variable is specified by the data column selected
for the
Category label field when the data
source was defined.
Here is
an example of a gauged graph display:
If the
gauged graph display does aggregate data, the gauged graph displays
data points at the average interval for each data series. The indexes
of the aggregated intervals are averaged to determine the interval
to display and the color of the bar.
Here are
some guidelines for using the gauged graph display:
-
To display the average interval
in a graph, the gauged graph is the easiest method to use.
-
The tooltip for each data series
indicates that the displayed value is the average interval.
-
To prevent aggregation by the gauged
graph display, aggregate the data at the data model level.
