Hi, I am hoping to use the FFT node - node-red-contrib-fft

It requires data in a certain format as follows:

```
{ "data" : [
{"accelerometer_x" : 9 , "accelerometer_y":2, "accelerometer_z":2},
{"accelerometer_x" : 7 , "accelerometer_y":2, "accelerometer_z":2},
{"accelerometer_x" : 5 , "accelerometer_y":0, "accelerometer_z":0},
{"accelerometer_x" : 7 , "accelerometer_y":2, "accelerometer_z":2}
]}
```

I receive MQTT data from a 3-axis accelerometer in this format:

`{"axis":"g","x":-0.919,"y":0.209,"z":0.258}`

Ths gives a bad data inject error.

Can anyone recommend a course of action to correctly format the data?

Thanks.
