Have you tried to use a top N filter on the chart?

This is most likely because the filter is happening before the
aggregation. Take a look at the topn example attached that aggregates
in the data set and then filters on the chart.

Ronan,
There are other ways around this all though it may involve a bit of
scripting. In fact you can replace all of the data a chart uses at run
time. I am not certain you want to do this. If you need some kind of
example let me know. BTW pie charts have min slice value that combines
smaller values into a "others" type category as well.

BTW another more elegant solution is to create a birt data cube off of
the data set and then drag the cube to the report. Ann a filter to it
and then convert it to a chart view. Take a look at the attached example.
