Using PROC GPLOT to produce PDF files with mouseover text on individual plot symbols

Hi:

I would like to share a technique I discovered for producing mouseover text in PDF files created by PROC GPLOT. In SAS 9.2 the PROC GPLOT option “HTML=” was introduced. This option allows plotted symbols to link to an HTML destination. The technique shown in the program below manipulates this option to provide a mouseover feature similar to that available in ODS HTML. The output PDF file is attached.

* Author: Bill Sukloff;

* Date: 2012-11-06

* Description: For PDF files, uses the option introduced in SAS 9.2 GPLOT of "HTML=" to display text when the mouse hovers over a plotted symbol;

* Caution: this feature may not work in some PDF readers (tested only in Adobe Reader);

DATA class_with_anno;

SET sashelp.class;

LENGTH anno_link $ 30;

* Normally you start the href text string with "http:". I found that replacing "http:" with ">:" looked nice and still resulted in the Adobe Reader interpreting the text string as an HTML link;

* Another option is to use a text string which simulates an arrow: "-->:";

IF name NE ''

THEN anno_link = "href='>:"!!TRIM(LEFT(name))!!"'";

ELSE anno_link = "href='>:No name'";

RUN;

OPTIONS orientation=landscape PAPERSIZE=legal NODATE NONUMBER;

ODS HTML CLOSE;

ODS LISTING CLOSE;

ODS PDF FILE='c:\temp\sasgraph_pdf_example_mouseover.pdf' style=BarrettsBlue;

TITLE1 'SAS/Graph: PDF Mouseover using fake HTML links';

FOOTNOTE1 'Note: Place your mouse cursor over a plot symbol for information about the data value';

PROC GPLOT DATA=class_with_anno;

PLOT height * weight = sex /

HTML=anno_link

;

RUN;

QUIT;

ODS PDF CLOSE;

Nice and thanks for sharing. I just sent you (well, hopefully it was your email address I found on the web) an email asking if you would be interested in turning this post into a 10-minute presentation for our upcoming (December 14, 2012) Toronto Area SAS Society meeting.

Thank you for sharing this tip. I believe that the HTML= option was available in earlier releases as well - perhaps as beta (?). BTW there is a missing semi-colon on the second comment in the first DATA step.
