Apply Exclusive Filter

Hi

I have a TreeMap graph of data, but in this scenario the majority of the data is taken up by Not Assigned / #.

Whilst this is correct (data is incomplete in source, hence it's showing up as such), it would be nice to give the user an option to remove the # value from analysis, so that the other values show up a bit better.

I know how to apply a filter on the dataset, but how to apply an exclusive filter.

DS_WEEK_SITE.setFilterExt("ZDASHBD", "87")

I want something like

DS_WEEK_SITE.setFilter("ZDASHBD" "<>87")

Any ideas ?

Regards,

Andrew
