Local Drill-Down Mode

The following example generates an HTML output file that runs the Graph applet. The applet automatically generates and displays drill-down graphs based on the element in the graph that was selected with a click of the left mouse button. In the example, note how variable roles are assigned in the VBAR3D statement.

This example is available in the Sample Library under the name GWBJALOC.

Script Drill-Down Mode

The following example shows you how to implement the Script drill-down mode in the Graph applet or Map applet. The program generates a map of the United States that responds to drill-down actions by displaying abbreviated state names . In the example, note how PUT statements are used to insert JavaScript into the ODS output file.

This example is available in the Sample Library under the name GWBSCDRL.

For further information, see Configuring the Script Drill-Down Mode on page 407.

URL Drill-Down Mode

The following example demonstrates URL drill-down mode.

This example is available in the SAS sample library under the name GWBURLDR. For further information, see Configuring the URL Drill-Down Mode on page 409.

 /* Enter the web-output-path. */  filename urldrill '  web-output-path  ';  filename sales '  web-output-path\sales.html  ';  filename central '  web-output-path\central.html  ';  filename south '  web-output-path\south.html  ';  filename west '  web-output-path\west.html  ';  /* Close the ODS listing destination to conserve resources. */  ods listing close;  /* Specify the device driver. */  goptions reset=global device=java;  /* Create the data set REGSALES. */  data regsales;     length Region State $ 8;     format Sales dollar8.;     input Region State Sales;  /* Initialize the link variable. */     length rpt ;  /* Assign values to the link variable. */  if Region='Central' then       rpt='href="central.html"';     else if Region='South' then       rpt='href="south.html"';     else if Region='West' then       rpt='href="west.html"';  datalines;  West CA 13636  West OR 18988  West WA 14523  Central IL 18038  Central IN 13611  Central OH 11084  Central MI 19660  South FL 14541  South GA 19022  ;  /* Open the HTML output file and specify the URL drill-down mode. */  ods html body=sales      path=urldrill      style=money      parameters=("drilldown"="url";  /* Create a chart that uses the link variable. */  title1 'Company Sales';  proc gchart data=regsales;     vbar3d region / sumvar=sales     patternid=midpoint     html=rpt;  run;  quit;  /* Create an HTML file for central sales drill-down. */  ods html body=central path=urldrill style=money;  /* Generate the first drill-down report. */  title1 'Central Sales';  proc print data=regsales noobs;     var state sales;     where region='Central';  run;  /* Create an HTML file for southern sales drill-down. */  ods html body=south path=urldrill style=money;  /* Generate the second drill-down report. */  title1 'Southern Sales';  proc print data=regsales noobs;     var state sales;     where region='South';  run;  /* Create an HTML file for western sales drill-down. */  ods html body=west  path=urldrill style=money;  /* Generate the third drill-down report. */  title1 'Western Sales';  proc print data=regsales noobs;     var state sales;     where region='West';  run;  quit;  /* Close the HTML destination and open the listing destination. */  ods html close;  ods listing;

HTML Drill-Down Mode

The following example generates an HTML output file that displays the Map applet. The applet is configured for HTML drill-down mode, where drill-down URLs are dynamically generated based on the data in the graph element that was selected in the drill-down action. In the example, note how the value of the STATENAME variable is used to complete drill-down URLs.

This sample is available in the SAS Sample Library under the name GWBJAMAP.
