I am working with graphite and node js. I want to aggregate two metrics called as test.abc and test.xyz. I want to check based on timestamp that the abc metric and xyz metric both have common data. Like intersection of data based on timestamp.

I am using graphite API URL along with multiply series function but, its not giving me correct results as expected. I am calling this URL in node js to render data on a UI.

Can someone please help in suggesting some correct function or method for aggregation.
