Can you elaborate? What’s your problem? It seems to be working well for me - I am currently focused on wrapping chart.js to render the plots and then I will write a little config script for easier setup and data selection, but maybe I can help you out.

I’m currently working on this. I’m writing a module that will include both Withings and Google fit and draw charts for the data that the APIs offer. I am in early development currently however, so it might take some time. I will post more details as they become available.
