AOI scan path analyzers
=======================
ArGaze provides ready-to-use AOI scan path analysis algorithms.
!!! note "Definition"
An [AOIScanPath](../../../argaze.md/#argaze.GazeFeatures.AOIScanPath) defined as a list of [AOIScanSteps](../../../argaze.md/#argaze.GazeFeatures.AOIScanStep) made by a set of successive fixations/saccades onto a same AOI.
The JSON samples have to be included inside [ArLayer configuration](../aoi_analysis.md) *aoi_scan_path_analyzers* entry to select an algorithm.
```json
"aoi_scan_path_analyzers": {
JSON sample
}
```
Read more about [AOIScanPathAnalyzer base class in code reference](../../../argaze.md/#argaze.GazeFeatures.AOIScanPathAnalyzer).
!!! note
The members indicated as **property** are what returns the analyzer.

```
## Lempel-Ziv complexity
::: argaze.GazeAnalysis.LempelZivComplexity.AOIScanPathAnalyzer
### JSON sample
```json
"argaze.GazeAnalysis.LempelZivComplexity.AOIScanPathAnalyzer": {}
```
## N-Gram

"n_max": 5
}
```
## Transition matrix
