Does Rowchart select only one bar in dc.js / crossfilter?

Question

I have a dc.rowchart that has 5 different "categories". All are selected first. When I press one, then only one is highlighted. When I click on the second ... both the first and the second that I clicked are highlighted.

How can I do this / set up a line such that only one category is highlighted each time I click on the panel?

dc.filter("category1");
dc.filter("category2");

Both of these sequences look like “add” filters than replace.
