Specify Label Width for Facet

[curran]

This is perhaps an issue where it's configurable already, but I just cannot find the way to configure it.

The issue is, I'd like to allocate more space for the labels of cities here, so the city names don't get truncated:

This is the spec I have:

{
  "$schema": "https://vega.github.io/schema/vega-lite/v2.json",
  "width": 805,
  "height": 52,
  "data": {
      "url": "data.csv"
  },
  "mark": "area",
  "encoding": {
      "x": {
          "field": "timestamp",
          "type": "temporal",
          "axis": {
              "title": "Time",
              "grid": false
          }
      },
      "y": {
          "field": "temperature",
          "type": "quantitative",
          "axis": {
              "title": "Temp °C",
              "grid": false
          }
      },
      "color": {
          "field": "city",
          "type": "nominal",
          "legend": null
      },
      "row": {
          "field": "city",
          "type": "nominal",
          "header": {"title": "City"}
      }
  }
}

You can see it running here: https://datavis.tech/edit/5a391ee51b1043c5ac7c8cb1fd0249e7

I've looked in the following places in the documentation to see if the label spacing is configurable:

• Faceting a Plot into a Trellis Plot
• Example: Styling Labels

The closest thing I've found so far is titleMaxLength for Axis, but I don't think that's the thing to configure for these labels.

Fingers crossed this is something easy to do already :)

Thanks for the great ongoing work!

Thanks for asking!

The underlying Vega may have an unintended text limit set -- please follow the issue that I have filed here.

In any case, I agree you should be able to adjust the underlying labelLimit, but we haven't implement it yet (as noted in #2446).

I'm gonna close this issue now as we have tracked both issues. Note that I have listed some instruction in the first part #2446 if you want to help contribute support for header label and title properties.
