Advice on Histograms / Resources for Training People.

I am working on a project which is tracking the progress of training courses being delivered to many organisations.

The WBS is split down thus:  Region > Organisation> Course

I have assigned to each Course 3 activities. Passed (a bar from project date until data date), Booked (A bar from data date running until the last course), Not Booked (TBC - for those employees who havent been booked on a course YET).

I want to be able to measure this using P6. I have assigned activity codes for Suppliers, Organisations, and Course titles.

So the resource graph i want to show would show cumulative numbers of Passed, Booked, and Not booked...... By supplier.

I do not want the graph to allocate these figure per month, i only want a cumulative of how many people per company have been passed, and how many have yet to train.

Any advice on how to show this graph, as when i run it in the way i would with labour, it is splitting the actuals along the duration.
