Hi I am using http://code.google.com/apis/chart/docs/gallery/googleometer_chart.html

I have:

<img src="http://chart.apis.google.com/chart?cht=bvg&chs=250x150&chd=s:egbdf&chxt=x,y&chxs=0,ff0000,12,0,lt|1,0000ff,10,1,lt&chm=o,000000,0,-1,10|V,000000,0,-1,1:15,,:4:10|H,000000,0,-1,3:9,,:8:17&chxl=0:|E|G|B|D|F" usemap ="#chart" />
           <map name='chart'>
                <area name='bar0_0' shape='POLY' coords= '124,440,124,499,143,440,143,498' href='#'>
                <area name='bar0_1' shape='RECT' coords='55,129,78,63' href='#'>
            </map>

When I use ‘rect’ for shape I can attach a click event etc but when I use ‘poly’ It doesn’t work.

I’ve use a jQuery mouse position plug in to check the coords and they seem ok.

Can anyone help please?

Thanks

    put image into something like paint and get it’s coordinates, not the coordinates on the web page Obviosuly, so it will still work anywhere on the page.
