As long as you can get the information you need to draw the chart from the element you mouseover, then this is fairly easy:
// element is the DOM element to attach the event handler to
element.onmouseover = function () {
// fetch the information you need from the element, then call the draw function, passing any necessary parameters
};
// element is the DOM element to attach the event handler to
element.onmouseover = function () {
// fetch the information you need from the element, then call the draw function, passing any necessary parameters
};
If you're looking to use this on chart elements, though, it becomes much more difficult, as the Visualization API doesn't expose a 'mouseover' event for the charts or any methods to link a DOM element back to its origin in the DataTable.
