The bar
chart with reference lines display applies a range to a standard graph
display such as bar chart or line graph. Here is an example of a bar
chart with reference lines display:
Here are
the properties that created the display:
For the
best results, the indicator data should return only one value for
each unique value in the
Category Label data
column. If the indicator data returns only one value, the bar chart
with reference lines display does not need to aggregate the data.
The category variable is specified by the data column selected for
the
Category Label field when the data source
is defined.
If the
bar chart with reference lines display does aggregate data, the bar
chart with reference lines 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.
If the bar chart with
reference lines display does aggregate data, the bar chart with reference
lines does two things:
-
It displays
data points at the average interval for each data series.
-
It averages
the indexes of the aggregated intervals to determine the interval
to display and the color of the bar.
Here are
some guidelines for using the bar chart with reference lines display:
-
To display the average interval
in a graph, the bar chart with reference lines 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 bar
chart with reference lines display, aggregate the data at the indicator
data level.
