Enclosing class:

GraphGeneral
```
public class GraphGeneral.GraphMouseListener
extends java.lang.Object
implements java.awt.event.MouseListener
```
GraphMouseListener, allows to drag'n drop with the mouse. Currently, this listener locates the coordinates of the mouse pointer and then checks what is beneath it: legends, labels, curves, points... Double-clicking then opens a context-sensitive dialog (to change the label-settings, for example).
