This sample uses the GCHART procedure in conjunction with the Annotate facility in the SAS/GRAPH software to create a single bullet graph indicator for use in a dashboard. This version is intended to used in a webDAV content portlet in SAS Information Delivery Portal software.

Note: Bullet graphs were invented by dashboard expert Stephen Few and are described in detail in Chapter 6 of Information Dashboard Design (Sebastopol, CA: O'Reilly Media, Inc., 2006).

For a sample of a complete dashboard, see Create a dashboard with multiple bullet graph indicators for use in a portlet.

To create a bullet graph similar to this sample, create a SAS data set that contains the following variables:

TITLETEXT

specifies the title or label above the bullet graph.

MYLABEL

specifies the bar midpoint label, which is displayed to the left of the bar.

ACTUAL

specifies the value for the dark bar that represents the actual value.

TARGET

specifies the value for the dark line that represents the target value.

RANGE1

specifies the maximum value of the first shaded area behind the bar.

RANGE2

specifies the maximum value of the second shaded area behind the bar.

RANGE3

specifies the maximum value of the third shaded area behind the bar.

VALUE_FORMAT

specifies the format that is to be used for the tick mark values on the axis.

BY_VALUE

specifies the tick mark increment for the values on the axis.

After you create your data set, run the %DO_BULLET macro, passing in as parameters the SAS data set name and the name of the graph. Here is an example:

%do_bullet(data1,bull1);

The %DO_BULLET macro uses the GCHART procedure to draw a horizontal bar chart (HBAR) in order to show the actual value as a dark bar. It then creates an Annotate data set that shades the three target ranges behind the bar using the Annotate BAR function in order to define the shaded rectangular areas. Finally, it annotates a thick line that represents the target value.

The %DO_BULLET macro assumes the base of the bar and the minimum of the first range is always zero. It also assumes that the bar value and target value for each fall within the viewable area that is covered by the three ranges.

For additional information about creating dashboard applications with SAS/GRAPH software, see SAS/GRAPH Dashboard Samples.
