This section describes two approaches for creating an interactive control chart which enables an end user to "drill down" into subgroup data points and display information not contained in the chart itself. For example, the end user might want to be able to click on a subgroup to

• list the individual measurements in the subgroup

• diagnose an out-of-control point by viewing a Pareto chart of the most common problems affecting the process

• view a list of recommended corrective actions

• trace the raw materials used to manufacture a batch of product

The two approaches for creating interactive control charts are as follows:

• saving graphics coordinate data from control charts for use in creating SAS/AF applications

• associating Uniform Resource Locators (URLs) with subgroups to produce "clickable" control charts in HTML

The options described in this section can be specified in all the chart statements available in the SHEWHART procedure.
