Hi, Sebastien Follow your instruction, I was able to create a Cube object and define sample_space. However, I don't know how to retrieve the measure result. Can you tell me how to do that? What do you mean by "instantiate a cube with a base queryset, and use one of the methods provided to calculate the statistics"
Thanks.
