Classe: Image_Graph_Dataset - X-Ref
Data set used to represent a data collection to plot in a chart| Image_Graph_Dataset() X-Ref |
| Image_Graph_Dataset [Constructor] |
| setName($name) X-Ref |
| Sets the name of the data set, used for legending param: string $name The name of the dataset |
| addPoint($x, $y = false, $ID = false) X-Ref |
| Add a point to the dataset $ID can contain either the ID of the point, i.e. 'DK', 123, 'George', etc. or it can contain values used for creation of the HTML image map. This is achieved using is an an associated array with the following values: 'url' The URL to create the link to 'alt' [optional] The alt text on the link 'target' [optional] The target of the link 'htmltags' [optional] An associated array with html tags (tag as key), fx. 'onMouseOver' => 'history.go(-1);', 'id' => 'thelink' param: int $x The X value to add param: int $y The Y value to add, can be omited param: var $ID The ID of the point |
