will assume the path is relative to the "current directory". The setSearchPath method allows you to specify the directory ChartDirector used to search for the file. You may specify more than one directory by separating the directories with semi-colons.

If you are using ChartDirector in a web server, note that the "current directory" may not be the same as the script directory. It depends on the web server. For example, for the Microsoft IIS, the "current directory" is the directory of the web server executable, which is usually inside [system32].

To ensure you are loading images from the script directory, you may use setSearchPath to specify the script directory. For example:

$c->setSearchPath(dirname(__FILE__));

Another thing to note is that setSearchPath expects a file system path, not a URL path. For example, the root of the path is the file system root, not the web server document root. If you are using a URL path, please map it to a file system path first before calling setSearchPath.

Arguments

Argument	Default	Description
path	(Mandatory)	A list of directories, separated with the path separator of your operating system (";" for Windows, ":" for Linux/UNIX).

Return Value

None

Arguments

Argument	Default	Description
name	(Mandatory)	The name of the session variable used to store the chart image. If there are multiple chart images in the same web page, each image must use a different name.
imageFormat	PNG	A constant representing the format of the image. Must be one of the pre-defined constants PNG, JPG, GIF, BMP or WMP.

Return Value

A string representing the query parameters for retrieving the image using the myimage.php utility.
