Report Table of Figures
This assesslet inserts a table of figures. No further settings are required for the assesslet except where to place it, see Common Assesslet Settings. To add figures to the table, go to the assesslet that has created the figure. This will either be a Report Image assesslet or Signal Graphic assesslet. In the Assesslet Content view, select the Include in table of figures checkbox.
If the figure has been added inside a Script assesslet, use the function
setIncludeInTableOfFigures(true) to add the figure to the table of figures.
