The drilldown in this example is done in the traditional SAS/Graph way,
but using the new "goptions device=javaimg" rather than gif ...
First, a character variable is created, containing the html tags for
the drilldown (href=) and the text charttip/rollover-text (title=)
as follows ...
length htmlvar $500;
htmlvar='title='||quote(
'State: '|| trim(left(st)) ||'0D'x||
'Population: '|| trim(left(put(population,comma12.0)))
)
||' '||
'href="http://www.state.'||trim(left(lowcase(st)))||'.us"';
Then that variable is specified using the "html=" option in the
SAS/Graph "proc gplot" as follows...
proc gchart data=mydata;
hbar st / discrete
type=sum sumvar=population
ascending
nostats
maxis=axis1
raxis=axis2
autoref cref=gray
clipref
coutline=black
cframe=white
html=htmlvar <-------- here!
des="" name="&name" ;
run;
The output is created using ODS HTML, and "goptions device=javaimg".
Device=javaimg is similar to device=gif, in that two output files
are produced - an html file containing the drilldown & charttip info,
and a png file containing the graph (rather than a gif file).
The person viewing the graph will view the html file, and it will
display the png file and line up the drilldown/charttip info in
the correct locations.
