24921 - Use PROC GPLOT to control the axis range with macro variables

Sample 24921: Use PROC GPLOT to control the axis range with macro variables

This sample code first uses PROC MEANS to calculate the minimum and maximum values in the input data set. These values are then used to create two macro variables, which are then used with the ORDER= option on an AXIS statement with PROC GPLOT to set the horizontal axis range.

The graphics output in the Results tab was produced using SAS® 9.2. Submitting the sample code with releases of SAS prior to SAS 9.2 might produce different results.
