That looks like a JSON string representing an array of one string “24.000” – wiring the output from your `http request` node to a debug node will show you the data type and structure more clearly. Usually, when a service returns the data as stringified JSON, wire the output to a `JSON` node to turn it into a real Javascript Object. Then you can use a `change` node to move the array element into `msg.payload`, which is where the chart and guage will look to find the value to be displayed…

This channel is for the development of Node-RED, this sort of question is better asked in #general

There’s a great page in the docs that will also be helpful:

Good catch, Mark – I don’t even notice the categories yet, it seems… but he will probably want to use #dashboard instead
