Set default font in vega lite

Can I set a font, e.g. in vega-lite's config object, that is used for all the labels and titles?

I currently set labelFont and titleFont for the x&y axis and the color legend, but it is the same font everywhere so it would be nice to set it just once.

Solution

Unfortunately no, there does not appear to be a global font setting in Vega-Lite. But you can set all fonts in the figure (for example to "monospace") with the following config:

"config": {
  "axis": {"labelFont": "monospace", "titleFont": "monospace"},
  "legend": {"labelFont": "monospace", "titleFont": "monospace"},
  "header": {"labelFont": "monospace", "titleFont": "monospace"},
  "mark": {"font": "monospace"},
  "title": {"font": "monospace", "subtitleFont": "monospace"}
}

Alternatively, if you have control of the browser page where the chart is being rendered, you can set the default font for the div that the chart appears in using standard CSS.
