We are glad to announce that our Analysis session has been improved with the recent launching of the Analysis V2!
Now, you can add your script written completely in Node.js using external libraries and debugging it on your own computer. We will continue to support V1 while developers work in the migration for the V2.
Check out the tutorial and code examples here http://docs.tago.io/en/latest/analysis.html
If you still have any question about the new Analysis, contact us!
