 Tooltip for data in linechart |

I have a line chart that have several lines. I am trying using addextraField to give extra information for each datapoint in the lines.
for($i=0;$i<$size;$i++){
$dataSetObj=$layer->addDataSet($dataSeries[$i], -1, $key[$i]);
$layer->addExtraField($data2[$i]);
}
$imageMap = $c->getHTMLImageMap("", "", "title='{dataSetName}, {value|2} ( {field1} %) {x|mmm dd, yyyy}'");
However, all lines share the same field value in each x points. For example, if the tooltip is "aaa" at line 1 at x=123, then it is also "aaa" at line 2 at x=123; however, I might want to display "bbb" at line 2 at x=123.
Any ideas on how to achieve this?
Thanks,
Em |

Hi Em,
Instead of {field1}, please use {dsdiField0}.
Hope this can help.
