getLabelCoor([ offsetX, offsetY ])

Gets the image map coordinates of the sector label as HTML image map attributes.

The image map coordinates will be in the following format:


where (x1, y1) and (x2, y2) are opposite corners of the box that encloses the sector label. The format is specially designed so that it can easily be incorporated into HTML image maps.

This method should be called only after creating the chart image (eg. using BaseChart.makeChart or BaseChart.makeChart2). The image map cannot be determined without creating the chart image first.

Argument	Default	Description
offsetX	0	An offset to be added to all x coordinates in the image map. This is useful if the current image will be shifted and inserted into another image. In this case, the image map will need to be shifted by the same offset.
offsetY	0	An offset to be added to all y coordinates in the image map. See offsetX above for description.

A text string representing the coordinates of the sector label in HTML image map attribute format.
