Hi Bill,
You may use addExtraField. For example, in a simple bar chart, in C#, the code is like:
BarLayer layer = c.addBarLayer(myData, ....);
layer.addExtraField(myArrayOfToolTips);
.....
imageMap = c.getHTMLImageMap("", "", "title='{field0}'");
In the above, the {field0} represents the tooltips in the myArrayOfToolTips array.
If you need further help, would you mind to inform me the exact chart type you are trying to draw?
Regards
