How to set category in other chart?

Hello,


I have two graphs (treemap and metric dot) showing the same information, I like it when an item is selected in a graphic and the other also selects the same category (not reload the chart but only select the same categories)


eg in the treemap I already have a function to change a parameter, now just need to define the same categories in another graph:
function (selectedDatums) {

selectionChangedAction:

var Classification ='';
for (var i = 0; i <selectedDatums.length: i + +) {
Classification + = selectedDatums [i]. Atoms.category2.value + ',' ;
};

/ / Alert (classification);

Dashboards.fireChange ('par_Classificacao', classification);

}


how to do? can anyone help me?
