This sample uses the Annotate facility and the GANNO procedure in the SAS/GRAPH software to create a series of dial meter indicators, and then uses the GREPLAY procedure to arrange the indicators into a dashboard. For a sample of an individual indicator, see Create a dial meter indicator for a dashboard.

The %DO_GAUGE macro is used to create different gauge charts of varying colors, ranges, and so on. For information on the %DO_GAUGE macro, see Create a dial meter indicator for a dashboard. The dashboard in this sample is not necessarily a complete dashboard, but is a starting point to show you how to create custom gauges and how to insert them into a dashboard. Also, although gauges are commonly used in dashboards, other chart types might be more appropriate for displaying your data.

The %DO_GAUGE macro in this sample is enhanced to accept a new parameter that specifies the name of the GRSEG in which the gauge chart is stored temporarily. Here is the syntax of the enhanced %DO_GAUGE macro:

%macro do_gauge(mydata, major_tick_by, minor_tick_by, titletext, foottext, grseg_name);

In this sample, the %DO_GAUGE macro is called four times, which stores four gauge charts in GRSEGs GAUGE1 through GAUGE4. It then uses the GREPLAY procedure with the l2r2 layout template to place the four gauges on the sample page. The l2r2 layout template is a standard template that ships with SAS. Here is the layout of the l2r2 template:

Here is the GREPLAY procedure TREPLAY action statement that draws the appropriate gauges into the desired areas of the l2r2 template:

   proc greplay tc=sashelp.templt nofs igout=work.gseg template=l2r2;
    treplay
    1:gauge1 3:gauge3
    2:gauge2 4:gauge4
    des='' name="&name";
   run;

Notice that GAUGE1 is replayed into area 1.

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

This is a custom gauge chart, created using good-old 
traditional sas/graph technology - namely annotated
'pies', lines and text.

The gauge is created by specifying the values for 
the start-angle and end-angle and color, for each
colored range/segment (you specify these as the
'segment's observations in data data set below), 
and also an observation in the dataset for the 
'arrow' (this is the pointer/arrow for the gauge).
