Filter Delegate Advanced - Different from drill

If you're not familiar with the basics of filter delegate, please refer to this article before continuing reading.

Almost all filter delegate use cases evolve around setting up ANOTHER dimension attribute to be the actual filter that is delegated when you make the drill.

This particular article set's up a filter delegate with different from and on the SAME dimension attribute when you drill.

That becomes a negative drill - please select the ones that are different from what I just chose.

This is something often required to filter out some outlier values that ruins the scale of graphs, pollutes the average, medain etc. 

How-to

So let's say you have a graph that visualizes sales per month like this:

Your normal drill would of course mean that if you clicked November - the rest of the data would be about november, but what if we try to reverse that?

I select the graph and set my filter delegate to be DIFFERENT FROM the SAME attribute (Month) that was used to bulid the graph.

Now drilling on the month November, will effectively give a filter that is DIFFERENT FROM NOVEMBER.

Like all the other Filter Delegate use cases, you would owe it to the end users, to explain (in a text box or similar) that you have set up a different from drill on this particular visual.
