This function allows you to specify the default properties of the nodes. Calling this function before defining the nodes allows you to apply default settings like color, shape,.. to all of them. Parameters are given trough a $Settings array. To learn more about this please read the Format array guide.

setNodeDefaults ($Settings="");

No parameters required.


It is possible to specify the following default settings with this array.



Following shapes types are allowed :

 /* pChart library inclusions */
 include("class/pData.class.php");
