fn json_sample_fields(sample: &str) -> Vec<SampledField>Expand description
The fields of the first row of a JSON array sample, in the order they are written there.
Read out of the text rather than through serde_json, whose maps sort an object’s keys and would so hand the chart its axes in alphabetical order. A quoted value is a string however numeric it looks, which is what tells a year apart from a label.
