Jesper,
This is my graph.php document. I haven't changed anything. It
is the original code from the download. I uninstalled everything
earlier and reloaded the pear files. I had Image_Graph-0.6.0 on there
and now I have Image_Graph-0.5.0. I don't believe this matters. I will
change it back to 0.6.0 later.
The base_graph_display.php file has a require_once ('Image/Graph.php');
statement.
Thanks,
Steve

* This causes a 'png' canvas to be created by default.
*
* Otherwise use a single parameter either as an associated array or
passing
* the canvas along to the constructor:
*
* 1) Create a new canvas with the following parameters:
*
* 'canvas' - The canvas type, can be any of 'gd', 'jpg',
'png' or
'svg'
* (more to come) - if omitted the default is 'gd'
*
* 'width' - The width of the graph
*
* 'height' - The height of the graph
*
* An example of this usage:
*
* $Graph =& Image_Graph::factory('graph', arrray(array('width' =>
400,
* 'height' => 300, 'canvas' => 'jpg')));
*
* NB! In ths case remember the "double" array (see {@link
Image_Graph::
* factory()})
*
* 2) Use the canvas specified, pass a valid Image_Canvas as
* parameter. Remember to pass by reference, i. e. &$canvas,
fx.:
*
* $Graph =& new Image_Graph($Canvas);
*
* or using the factory method:
*
* $Graph =& Image_Graph::factory('graph', $Canvas));
*
* @param mixed $params The width of the graph, an indexed array
* describing a new canvas or a valid {@link Image_Canvas} object
* @param int $height The height of the graph in pixels

Hi Steve,
Could you please provide some code of what you are actually doing, I'm
shooting in blind here!
What I mean by "class id" is the name of the class or the alias. The
factory method simply instantiates the class and does the include for
you in at the same time, so you need to write something like
$Plotarea =& Image_Graph::factory('plotarea');
What it looks like is that you have done something like:
$Plotarea =& Image_Graph::factory('');
Although that might not be the case which is why some could would help
alot!
And for the future please:
1) Write only to one mailing list
2) Reply-all so the mailing list will also receive the answer (so that
others may use the information)
