The `data` property of a dataset can be passed in various formats. By default, that `data` is parsed using the associated chart type and scales.
## Primitive[]
```javascript
data: [20, 10],
labels: ['a', 'b']
```
When the `data` is an array of numbers, values from `labels` array at the same index are used for the index axis (`x` for vertical, `y` for horizontal charts).
This is also the internal format used for parsed data. In this mode, parsing can be disabled by specifying `parsing: false` at chart options or dataset. If parsing is disabled, data must be sorted and in the formats the associated chart type and scales use internally.
