This sample uses the GCHART procedure in conjunction with the Annotate facility in the SAS/GRAPH software to create a single slider chart indicator for use in a dashboard. For a sample of a complete dashboard, see Create a dashboard with multiple slider chart indicators.

In this sample, macro %DO_RANGE is used to create a chart that shows three ranges of data and a triangular marker that points to an actual data value. Each data range is represented by a specific color on the slider scale. The syntax of the %DO_RANGE macro is as follows:

%do_range(pltname,val1,val2,val3,val4,actual,color1,color2,color3,alertColor,valFormat,'titleText');

Here is a description of the macro parameters:

pltname

specifies a name for the plot. The maximum length is eight characters.

val1

specifies the lowest numeric value of the first (lowest) range.

val2

specifies the highest numeric value of the first range.

val3

specifies the lowest numeric value of the third (highest) range.

val4

specifies the highest numeric value of the third range.

actual

specifies the numeric value for the triangular pointer marker.

color1

specifies the color for the lowest range.

color2

specifies the color for the middle range.

color3

specifies the color for the highest range.

altertColor

specifies the alert color. Any range that uses the color &LIGHT_RED is changed to the alert color if the marker value is within that range.

valFormat

specifies the format that is to be apply to the numeric values.

titleText

specifies the text for the title that is to appear above the graph.

For this sample, you do not have to add your data to a SAS data set. Instead, run the %DO_RANGE macro and pass in all of the values as macro parameters. Here is an example:

%do_range(itcost,10000,30000,40000,50000,32000,&light_green,&light_yellow,&light_red,&alert_color,comma8.0,'IT Cost');

Here is the slider chart that this sample generates:

With this sample program, if the actual value falls within a range that is represented by the &LIGHT_RED color, the color of that range and the pointer is changed to &ALERT_COLOR. For example, if the actual value in the previous example is changed to 40,458, it generates the following slider chart:

Notice that the color of the 40,000 to 50,000 range and the pointer is now bright red (&ALERT_COLOR), which indicates an alert condition. Using soft colors for the three ranges and a bright color for the alert color makes an alert condition more apparent to the viewer. This is a good practice, but the implementation in this sample is not ideal. Any one or more of the ranges can be considered an alert range, which might not be the top or bottom range. Also, the GCHART procedure assigns colors indirectly through pattern statements rather than directly through a variable such as an annotated triangular marker.

/* The following "do_range" macro creates a slider chart indicator showing 
a three-segment bar with a pointer to indicate your current value.  

This example assumes that the color specified in the light_red variable 
indicates an undesireable range of values.  If the pointer falls in a 
range represented in the light_red color, it is set to the color specified 
in the alert_color parameter to indicate that it needs attention.

Note that the range for undesireable values does not have to appear at 
the top of the scale. It could be at the bottom, both bottom and top, 
or in the middle, depending on the color parameters that you specify in 
the macro call.

The do_range macro accepts the following list of parameters:

pltname = name of GRSEG to store the chart
val1 = lowest value of lowest range in scale
val2 = highest value of lowest range in scale
val3 = lowest value of highest range in scale
val4 = highest value of highest range in scale
actual = actual value for indicator (value for pointer)
color1 = color for lowest range in scale
color2 = color for middle range in scale
color3 = color for highest range in scale
alert_color = bright attention-grabbing color if value is in "alert" range
valfmt = format to apply to the values
titletext = title to print above individual chart
