Dynamic axis formatting / scale?

Hi,

I’m trying to build a stacked area chart, that reacts on a signal for toggling between absolute and normalized values. The absolute values are in a currency domain and the normalized ones are percentages.

Is there any way to set an axis’ format and scale properties from a signal?

Hi everyone, this issue is a holdout from Vega 2, and has been partially addressed in Vega 3.

• You should now be able to use a signal to dynamically set the format property.
• You can not dynamically set the scale property. Information about the specific scale (in particular, its type) is used within the Vega parser to determine the appropriate output. However, there is flexibility around which data fields are used to parameterize a scale – so you can get dynamic axes by changing the underlying scale instead. For an example, see https://vega.github.io/vega/examples/scatter-plot-null-values/

As we do not currently intend to make changes here, I’m closing out the issue.

@jazzido Also remember to relocate the scale references in marks from enter to update if you want them to be dynamic.
