>I have an application that has about 40 graphs stored in a general field of a table. The application then passes the current data to the graph for display. Simple application. Problem, the table is 80 mg. Is there a better way of doing this. Maybe creating the graph on the fly rather than storing the graph in a general field. Any advise would be helpful.

Robert,
MSGraph could be managed by OLEAut. so create them on the fly. If it's MSGraph8 then run excel and record macro to create the same graph type. Get macro code and do some furnishing to fit it to VFP syntax. Here is a little sample that does all on the fly :

*** set the LOCALEID to English
nlLocaleId=sys(3004)		&& Save local id
=sys(3006,1033)				&& We will be sending instructions in English
