Hi all,

I use Filebeat to fetch data from 2 Arduinos via the UDP interface. The messages are formated within the Arduinos and are sent in JSON format:

```auto
"message": {
      "FFT_Freq": [
        0,
        78.125,
        156.25,
        234.375,
        312.5,
        390.625,
        468.75,
        546.875,
      ],
      "FFT_Magn": [
        3394.808,
        1488.456,
        15.87906,
        54.76368,
        17.0278,
        86.5359,
        133.0211,
        81.6696,
      ],
      "cnt_Tx": 6565,
      "deviceID": "CurSensor_MCU",
      "t_Tx": 2144553233,
      "MCU_current": 101.1
    }

```

The FFT\_Freq and FFT\_magn fields contain a signal's FFT Frequencies and respective Magnitudes. Of course FFT is not "time-variant" to display it as time-series, but it would be nice if I could visualize I kind of X-Y plot, with X being the Frequencies and Y the respective magnitudes, and these would be refreshed each time a new message arives in Kibana.

Is there a way I can achieve that in Kibana?
