Hi @noob96 What @zenofmud is saying (in visual terms) is...

 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/1/9/19ee517de8c52d7b27d9ea9cae198a58678e910d.png)

Have a read of this thread - I visually explained this process for someone else [here](https://discourse.nodered.org/t/manipulate-vector-for-dashboard-chart-node/25298/3)

some clues...

- for changing a string number to actual number - search for "javascript `parseInt`"
