Creating Drill-Down Graphs in HTML

Attaching Links to the Primary Chart

You've already created the initial chart you want to use. Now it's time to modify the code for the chart to create the primary chart and attach links to it.

First, let's look at the code that created the chart you are using:

goptions hsize=5in vsize=4in; title 'Total Sales by Year'; proc gchart data=work.saletrnd; vbar year / subgroup=prodtype discrete sumvar=actual; run;

To create the drill-down graph, change the GOPTIONS statement to specify GIF output and a size for the SAS/GRAPH chart.

goptions device=gif xpixels=480 ypixels=360;

Next, add the HTML= option to the VBAR statement. The HTML= option assigns elements of the chart to the variable you created to hold the HREF address strings (PriDrill). In turn, the HTML= variable identifies the link destination variable to the GRAPH procedure for use in creating the image map in the HTML output file.

goptions device=gif xpixels=480 ypixels=360; title 'Total Sales by Year'; proc gchart data=work.saletrnd; vbar year / subgroup=prodtype discrete sumvar=actual html=pridrill; run;
