How do I get value from an array

General
1

I have the following array which feeds a to chart node, I want to send it through a function node or a change node and extract "Saturday" to a msg.payload but everything I tried failed I just cannot get it.
Thought it would be something like msg.payload = msg.payload[0]lables[0]; any help would be appreciated, thanks.

This page in the docs explains how you can use the debug sidebar to find the path to any message element: https://nodered.org/docs/user-guide/messages
