Draw radar chart with different axis

I am using this library to draw radar chart and it is very useful. Problem is now I need to draw different min, max value and I don't know where to put min, max option for each axis. How shall I do?
Do I need to normalize? If so, can you please guide?
```
"quality": {
"min": 0,
"max": 40.0,
"realMax": 40.0,
"points": 0,
"kpiMeasurableList": null
},
"bonus": {
"min": 0,
"max": 20.0,
"realMax": 20.0,
"points": 0,
"kpiMeasurableList": null
},
"demerit": {
"min": -20.0,
"max": 0,
"realMax": 0,
"points": 0,
"kpiMeasurableList": null
},
"risk": {
"min": 0,
"max": 20.0,
"realMax": 20.0,
"points": 0,
"kpiMeasurableList": null
},
"productivity": {
"min": 0,
"max": 40.0,
"realMax": 40.0,
"points": 0,
"kpiMeasurableList": null
}

```

The issue names no source file, test, or API entry point to start from. Review the radar-chart implementation and its axis configuration, then determine whether per-axis minimum and maximum values are supported or need a documented approach. Done should include a clear answer or an implemented, tested way to render axes with different ranges.
