HKey

java.lang.Object
- jhplot.HKey

All Implemented Interfaces:

Serializable
```
public class HKey
extends Object
implements Serializable
```
Create an interactive key label in the USER or NDC coordinates. The label can be defined in the NDC (normalized coordinate system) or the user coordinate. Only one line of the text can be shown. The key is not related to any data set, so you can plot this key even if no data are shown.
