Hi, i'm new with Kibana and Vega,  
I visualizated data that i entered manually and i noticed that when i enter a field name containing a dot (.) the visualization doesn't show up but when i remove the dot it works fine.  
The problem is that the data base that i'm currently using contains a file names with a dot  
What can i do in this case ?

Could you please share your [Vega Spec](https://www.elastic.co/guide/en/kibana/current/vega.html#asking-for-help-with-a-vega-spec)?

Use `['process.name']` to make that work when there are `.` in your field names.

Try this instead.

You data will come in as `process.name` so you can't change that in your data block. To make this easier just do a transform like I did below and rename that field to something without a `.` and then you can use that.

```auto
{
  "$schema": "https://vega.github.io/schema/vega-lite/v5.json",
  "description": "A simple bar chart with embedded data.",
  "data": {
    "values": [
      {"process.name": "A", "b": 28}, {"process.name": "B", "b": 55}, {"process.name": "C", "b": 43},
      {"process.name": "D", "b": 91}, {"process.name": "E", "b": 81}, {"process.name": "F", "b": 53},
      {"process.name": "G", "b": 19}, {"process.name": "H", "b": 87}, {"process.name": "I", "b": 52}
    ]
  },
    "transform": [
    {"calculate": "datum['process.name']", "as": "processName"}
  ],
  "mark": "bar",
  "encoding": {
    "x": {"field": "processName", "type": "nominal", "axis": {"labelAngle": 0}},
    "y": {"field": "b", "type": "quantitative"}
  }
}

```
