Subtitle not updating with selection from same graph

[atowriss99]

HI,

I have a graph as below, which contains a subtitle(shown below) containing Text and Measures.  I have other visuals on the page, which when I choose a product(x-axis of this graph) from those , the subtitle updates correctly.  However, when I click on a product in this graph's x-axis, the subtitle does not update.

Am I doing something wrong, or is it because the graph itsn't filtering itself?

Thanks
