It is possible to add multiple plots to the same graph, not only withing the same plot, i.e. you can have 2 or more
Image_Graph_Plotarea specified within the same graph.
The way Image_Graph handles this is utilizing the same method that Java does. This means that when you have 2 elements
that you can layout onto the graph, you specify whether they are vertically or horizontally aligned (and at which
percentage of the total width/height the split is positioned). This means that you define that "the area covered by
this layout, shall be shared by this percentage between these 2 elements". An example:
Layouts can be nested, so it is possble to define more than one arrangements:
Not only Image_Graph_Plotarea can be "layouted" all subclasses of the abstract class
Image_Graph_Layout can be layouted.
These are: Image_Graph_Plotarea, Image_Graph_Legend and Image_Graph_Title
