How can I access the 'Tag' of each brushed object?

Here's a simple example of what I want to accomplish using two lines.(Note: In this example the 'Tag' fields are empty, but let's assume that in my real application they contain text information...)

plot(1:1:9,9:-1:1); hold on; plot(1:1:9,1:1:9,'r');

When I brush a number of graphics objects > right click > Create Variable, the following dialog pops up. It shows the brushed objects, the Type, and the Tag. I would like to extract the information from the 'Tag' field.

I tried this, but it just returned an empty GraphicsPlaceholder array.

>> findobj(gcf,'-property','BrushData')

I'm using R2015a. Most of the examples I found seemed to be from older versions of Matlab, so maybe something changed with HG2?
