Onmouseover event not firing while using tooltips

[anitha]

I need to get a tooltip over the datapoints of png chart created using Chartfx7.0. I used the following piece of code.

ch.setRenderFormat(imagetype);

ch.setToolTipFormat("?',%S,%N,'" + imageMapName + "','");

ch.getAllSeries().getLink().setReload(false);

ch.getImageSettings().setInteractive(true);

ch.getImageSettings().setToolTips(ImageToolTipStyle.WITH_MOUSE);

ch.getAllSeries().getLink().setUrl(jumpURLBase+jumpURLParameters);

and got the area tag as follows

<area shape="poly" coords="654,16,654,20,680,20,680,16" href="javascript:DoDrillDown(0,22)" onmouseout="popupoff()" onmouseover="popupon('?',0,22,'ImageAvMap','',event)" />

But my onmouseover event is not getting fired when i move the mouse over the datapoints. I have written the popupon and popupoff functions correctly.

The onmouseover event got fired and I got the tooltip. Actually the map tag name and the usemap attribute value of the img tag( obtained using the method "renderToStream(OutputStream content, Writer imgMap, Writer htmlTag)" ) were not matching and that was the reason for mouseover event not getting fired.
