How to use Image_Graph

Before we start getting concrete by code examples here is a little explanation of how Image_Graph works.

The "layer" mode

Image_Graph works by using layers. That is every element you specify in Image_Graph is a layer on another layer (ultimately the Image_Graph is not on another layer but holds the canvas the other layers are drawn on.

1 ... 2 $Plot =& $Plotarea->addPlot(new Image_Graph_Plot_Line()); 3 ...

1 $Graph = new Image_Graph(800, 600); 2 $Plotarea =& $Graph->add(new Plotarea()); 3 $Plot =& $Plotarea->addPlot(new Image_Graph_Plot_Line( 4 new Image_Graph_Dataset_Random(10, 20, 100)) 5 ); 6 $Graph->done();
