SAS: how to customize the plots

SAS: How to Customize the Plots

• Usually I prefer to get a dataset of estimates for the plot, then use PROC SGPLOT/GPLOT, R!, or MS Excel plot those estimates.
• Or, modify the template of a statistic plot following the steps:
• Turn on the trace function: "ODS TRACE ON;"; run the PROC XXX; then find the name of default template (such as 'Stat.Lifetest.Graphics.cifPlot'); then "ODS TRACE OFF;"
• Print out the template: "PROC TEMPLATE; SOURCE Stat.Lifetest.Graphics.cifPlot; RUN;"
• Copy the definition from the log window
• Paste it in underscore part: "PROC TEMPLATE; _________; RUN;" and modify the definition part you are interested in, and run it
• Run the PROC XXX again.
• After done: run "PROC TEMPLATE; DELETE Stat.Lifetest.Graphics.cifPlot; RUN;" to set the template as the default format.

• May use the "Tools -> ODS Graphics Editor" to edit these plots after you get them. It's better use SGE format by setting "ODS LISTING SGE=ON; ODS HTML SGE=ON;"
