Remember that the bars in your primary chart are linked to pages by the values defined for PriDrill.

if year=1995 then pridrill='HREF="sales95.html"'; if year=1996 then pridrill='HREF="sales96.html"'; if year=1997 then pridrill='HREF="sales97.html"'; if year=1998 then pridrill='HREF="sales98.html"';

Now you need to create sales95.html, sales96.html, and so on. Continue as before, using ODS HTML statements to write the HTML pages and PROC GCHART steps to create the GIF charts. Since each chart must show sales for only one year, use a WHERE statement within each PROC GCHART step to limit its data to a specific year.

ods html body='sales95.html'; title 'Sales for 1995 by Quarter'; proc gchart data=work.saletrnd; vbar quarter / sumvar=actual subgroup=product discrete; where year=1995; run; ods html body='sales96.html'; title 'Sales for 1996 by Quarter'; proc gchart data=work.saletrnd; vbar quarter / sumvar=actual subgroup=product discrete; where year=1996; run; ods html body='sales97.html'; title 'Sales for 1997 by Quarter'; proc gchart data=work.saletrnd; vbar quarter / sumvar=actual subgroup=product discrete; where year=1997; run; ods html body='sales98.html'; title 'Sales for 1998 by Quarter'; proc gchart data=work.saletrnd; vbar quarter / sumvar=actual subgroup=product discrete; where year=1998; run;

Note that each graph gets a new TITLE statement. The net result is a set of pages displaying the graphs shown at half-size below.

	sales95.html	sales96.html
	sales97.html	sales98.html
