onmouseover isn't one of the API's events, and depending on how the chart is embedded in the page, your showMap() function might not be in scope. If it is, then what you have might work.
If you want to pass a reference to the object calling a function, use <div onmouseover="showMap(this);">, where "this" is a self-reference to the <div>. That won't get you access to the chart, though. Maybe if you declare your chart as a global, you could do something like: <div onmouseover="showMap(row, column);">, where row and column are the index values of the table cell. Then in the showMap() function, you can reference the global chart variable and pull the data you want based on the row and column indices. -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
