drill down based on legends
I have a work around solution, not quite as elegant as drilling down the legend but workable.
For each level in the hierarchy create a Filter, then for each filter level create a chart and use the filter level as the legend.
e.g. if the levels are Product Category and Product Sub Category, then create two filters, one for Product Category and the other for Product Sub Category
Then for the charts, chart 1 had Product Category on the legend and Chart 2 had Product Sub Category as its legend.

That's the whole point, you want to avoid to have to use 2 charts..
For me it's not about avoiding two charts but reducing clutter in the 2nd level chart.
e.g. Assume Product Category contains 2 categories of vehicles, 4 wheeled and 2 wheeled, and the Product Sub Category contains for 4 wheeled vehicles trucks, cars and vans and for the 2 wheeled vehicles scooters, sports bikes, cruisers and dirt bikes.
Selecting the 2 wheeled vehicles on the Product Category filter dynamically updates the Product Sub Category filter and chart to only show the scooters, sports bikes, cruisers and dirt bikes without the clutter of the 4 wheeled vehicles.
Like I said before it's an alternative solution. I would still prefer to drill down on the legend, but until then this works for me.
If you want just one chart, another solution is to use a dynamic switch measure, where the filter dynamically changes the measure that is displayed on a single chart. Basically one creates measures for each item to be filtered in the 1st and 2nd levels and then one uses the filter to select which of those measures is displayed in the chart.

Wouldn't suit 'Edit Interactions' better for what you're trying to do? Turn the first graph into a slicer for the second graph?
you are completely right!
