I’m guessing you’re looking for something like this?

As you can see, it’s been designed but not implemented yet & as far as I know, we don’t know when it will be.
I have a feeling that this sort of thing might be difficult to implement without missing some user’s requirements. So you might have to stick with exporting the data (not yet available for Android users) & doing this analysis in Excel for now. A third party developer could build an app, like these, to enable this sort of reporting, once the API is ready though or I could be wrong about this being unlikely
