# categoryOrder

A list of every category value for the axis in the order they appear visually in the graph or legend.

## Declaration

```swift
var categoryOrder: [String] { get set }
```

## Discussion

Discussion If your categorical axis represents, for example, blood type data, and the legend lists AB, A, B, O in that order, provide an array that contains the strings "AB", "A", "B", and "O" in the same order.
