In Internet Explorer, it is necessary for you to install a charting (Active X) control. The charting control is a supporting file that enables you to display any page containing a chart. This process only needs to be performed one time, and has been initiated because you have requested your first chart.
From an Internet Reporting Services Standard Report, click Charts. Note: You may wish to print these instructions for easy reference.
Select a chart from the Select Chart dialog box. The Security Warning dialog box displays (see below) asking you if you wish to install the Chart FX Internet Edition Client (charting control).
Click Yes. Your requested chart displays.
