How to get more than 7 dimensions from google analytics
I am trying to fetch data from Google Analytics. I came to know that we can fetch only 7 dimensions at once. But here I need to fetch more than 7 dimensions with correct metrics. Is there any way (other than using paid google analytics) to fetch more than 7 dimensions with correct metrics from google analytics.
If not, then is there any mathematical formula through which we can find intersection of dimensions fetched using 2 different queries having one dimension in common.
