25505 - Specify logarithmic axes using PROC GPLOT

Sample 25505: Specify logarithmic axes using PROC GPLOT

This example uses PROC GPLOT with the AXIS statement options LOGBASE and LOGSTYLE to produce a log scale axis.

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.
