ved using Box.getImageCoor. This allows <AREA> tags for TextBox objects be created easily.

(For TextBox, there is no "getHTMLImageMap" method. It is because each TextBox object only has one hot spot. It is more convenient to enter the handler URL and tool tip text directly into the <AREA> tag, rather than generating them using getHTMLImageMap.)

In this example, the image map coordinates of the chart title, vertical mark label, and the copyright message are obtained using Box.getImageCoor:

$titleCoor = $title->getImageCoor(); $markCoor = $mark->getImageCoor(); $copyRightCoor = $copyRight->getImageCoor();

The image map coordinates are then used to make <AREA> tags as follows:

<area <?php echo $titleCoor?> href='javascript:doSomething();' title='The title is clickable!'> <area <?php echo $markCoor?> href='javascript:doSomething();' title='The "Merge with Star Tech" text is clickable!'> <area <?php echo $copyRightCoor?> href='javascript:doSomething();' title='The copyright text is clickable!'>
