Details

Note that this function is coded to work automatically when using automatic exportation with HTMLStart. When using manualy, user should pay attention to the GraphDirectory option, so that graph files are in the same directory as HTML output files. When using to write reports in a non interactive way, first generate the graphic using a device and then use HTMLInsertGraph.

Value

no value returned.
