Hi David, first... this is an excellent article, really works for me. But I have a question. On reporting services I use dates parameters, and this are like:

start_datetime between @startdate and @enddate

but I have a problem with this. If my gantt bar start before my startdate I can't see my bar. I only see all the complete bars who start between this parameters. Do you know how to set or what can I do to could show in my gantt the partially part of bar just for the parameters that place.

I don't speak english so well, and I don't know if You could understand me. I attach a picture of my gantt.

Thanks for your time.

Regards.

Roberto
