Creating Drill-Down Graphs in HTML

Creating a Variable for Link Locations

To associate bars on the chart with HTML files, you start by creating a variable to hold the HREF addresses for the secondary files. You'll add the variable to the data used to create your chart. In our example, the variable is added to a temporary copy of Finance.Prdsal2.

Creating a variable

Because HREF links are long text strings, use a LENGTH statement to define the new character variable.

General form, LENGTH statement:
LENGTH variable(s) <$> length;

where

variable(s) names the variable to be assigned a length
$ indicates that the preceding variable is a character variable
length is an integer that specifies the length of the variable.

For this example, we will use a LENGTH statement to create a character variable (PriDrill) with a length of 40.

data work.saletrnd; set finance.prdsal2; length PriDrill $ 40; run;

PriDrill will store the names of the pages to load when users click the bars of the chart.
