there is no documentation on conditionals that I can find
jjwAmtelco opened this issue · comments
this json works fine in the editor but there are no examples of it in the documentation; or anywhere else that I can find. I know this is not a bug per say, But I would be glad to add documentation if I could figure this one out...

In most cases we transform options from snake case to camel case and everything from Vega-Lite is supported. The idea is that mirroring examples from Vega-Lite docs should be fairly automatic, in this case you could do:
|> Vl.encode(:color,
value: "green",
condition: [test: "datum['ScorePercentageCalc'] < 0", value: "red"]
)It's not practical to cover all examples from Vega-Lite docs, but a PR to the docs is welcome :)
just one tiny change; its 'test' not 'text' :-)
@jjwAmtelco yeah, I edited on GitHub, but this doesn't propagate to email notifications :D
