Hi Sebastiaan,
The oid's you use are probably of the 'gauge' type.
If you want to graph these values you have to add 'gauge' at the options line.
The reason:
By default MRTG calculates the rate per second: ((current value - previous value) / number of elapsed seconds)
Because usualy gauge values don't change by more than 300 in a 5 minutepoll interval the result is an empty graph if you don't use the gauge option.
Any mibbrowser can tell you what type of oid you are dealing with (Integer32, Gauge, timeticks, etc.)
Hth,
Jan.

However, the first time MRTG grabs the data, it gets values. but after that it does not return any value.
