The Earned Value Management Macros

%EVG_VARIANCE_PLOT

This macro is used to generate a plot of the cost and schedule variance against time; it features threshold plots obtained from the Planned Value, plus or minus 10%. The vital statistics of Planned Value, Earned Value, and Actual Cost are listed in the legend.

%EVG_VARIANCE_PLOT < ( parameters ) > ;

Note: %EVG_VARIANCE_PLOT requires output from %EVA_METRICS.

Optional Parameters

ACRONYMS=long

specifies whether the long form of the earned value acronyms is to be used - e.g., BCWP versus EV. The short form is used unless the macro variable _ACRONYMS_ is set to "long" or ACRONYMS=long is specified. The parameter overrides the macro variable setting; i.e., specifying any non-null value other than "long" for the ACRONYMS= parameter produces short forms.

METRICS=SAS-data-set

identifies the periodic metrics data set produced by the %EVA_METRICS macro, the name of which is determined by the METRICS= parameter of %EVA_METRICS. The default data set name is METRICS.

PLOT=SAS-data-set

specifies the name of the output data set. This is an internal data set that is used as input to the plotting procedure.

The default data set name is PLOT.
