Hi,

I am currently working with an IoT related dataset which has a datefield, machine types, status of those machines and voltage taken at various part in the machine (VID\_xx).

These VID\_xx columns are around 100 in numbers. My aim is to plot these voltages with time. Because there are almost 100 different columns, I do not want to plot them in a single chart.

I have worked with dropdown controls in Kibana where the field values can be filtered.  
I am wondering if I can have a chart with a dropdown with which I can select the voltage fields (eg: VID\_1 or VID\_2) I want to visualize. The x-axis will be same for all i.e timestamp.

Or, if anyone can suggest a better way of handling this scenario.

This could be possible if your data in Elasticsearch is structured differently so that each `VID_xx` has its own document. For example:

```auto
{
  "part_name": "VID_01",
  "machine_id": "abc",
  "date": ...,
  "voltage": ...,
  ...
}

```

Then you could easily use dropdown controls to filter based on `part_name`, or multiple parts, and even in combination with one or more machines.
