setHTMLImageMap(url[, queryFormat[, extraAttr[, offsetX, offsetY ]]])

Override the default arguments used when generating HTML image map for the layer.

BaseChart.getHTMLImageMap can be used to generate HTML image map for the whole chart. When BaseChart.getHTMLImageMap is used, the image map for all layers will be generated based on the arguments supplied to BaseChart.getHTMLImageMap.

The setHTMLImageMap method can be used to override those arguments for a chart layer, so the image map for that layer can be different.

For a detail description of image maps, please refer to BaseChart.getHTMLImageMap.

Argument	Default	Description
url	(Mandatory)	The URL to be used in the "href" attribute of the image map. Parameter substitution and formatting is supported. If no href attribute is needed (e.g. the image map is for onmouseover events only), use an empty string as the URL.
queryFormat	""	A text string representing the template of the query parameters to be appended to the URL. Parameter substitution and formatting is supported. An empty string means the default query parameters will be used (see table above). To disable query parameters, use a space chartacter as the queryFormat.
extraAttr	""	A text string to specify additional attributes to add to the <area> tag. Parameter substitution and formatting is supported.
