Bar chart legend to be interactive

[Anonymous]

Hi All,

I have a requirement for a bar chart where I am having 3 expressions A,B,C which is a stacked bar graph. When i click on Blue colour legend i.e A the blue bars only should show up , and for other two expressions also the same must be achieved.

I am not sure like how we can achieve this for the expressions. I tried with valuelist but it doesnt work. Any inputs to achieve this would be helpful
