How to filter dimension by another variable in Crossfilter

Question

My data has different columns, two of them are "date" and "node". I've created a date dimension called dateDim, simple enough. Now I'd like to filter that dimension based on the value of a certain node, this is, get all the values from dateDim whose node value equals a certain string. Is there any other way of doing so without adding the "node" variable as a key in the dimension definition?

Thanks in advance.

Answer 1

Not sure if this is what you mean but creating another dimension nodeDim and filtering on it will automagically impact dateDime. This is the crux of what crossfilter does.
